6 Application and Implementation

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality.

6.1 Application Information

6.1.1 Amplifier Topology

The topology chosen for the LMC603x, shown in Figure 6-1, is unconventional compared to general-purpose op amps. The LMC603x incorporates novel op-amp design that enables a wide input common-mode range and rail to rail output swing even when driving a large load. The input common-mode range includes ground, making the LMC603x an excellent choice for single-supply applications. While the LMC603x supports both a wide supply and common-mode voltage range, large input common-mode voltage can cause a degradation of input bias current performance. 16V Differential Front End Ultra-Low Bias Rail-to-Rail IN+ IN OUT LMC603x Figure 6-1. LMC603x Circuit Topology (Each Amplifier) The large signal voltage gain while sourcing is comparable to traditional bipolar op amps, even with a 600Ω load. The gain while sinking is greater than most CMOS op amps as a result of the additional gain stage; however, under heavy load (600Ω), the gain can be reduced as indicated in Section 5.6.

6.1.2 Compensating Input Capacitance

The high input resistance of the LMC603x op amps allows the use of large feedback and source resistor values without losing gain accuracy due to loading. However, the circuit can be especially sensitive to the printed circuit board (PCB) layout when these large-value resistors are used. Every amplifier has some capacitance between each input and ac ground, and also some differential capacitance between the inputs. When the feedback network around an amplifier is resistive, this input capacitance (along with any additional capacitance due to circuit board traces, the socket, and so on) and the feedback resistors create a pole in the feedback path. In Figure 6-2, the frequency of this pole is: f p = 1 2 π C S R P (1) where C S is the total capacitance at the inverting input, including amplifier input capacitance and any stray capacitance from the IC socket (if one is used), circuit board traces, and so on, and R P is the parallel combination of RF and RIN. This formula, as well as all the following formulas, apply to inverting and noninverting op-amp configurations. When the feedback resistors are smaller than a few k Ω, the frequency of the feedback pole can be quite high, since C S is generally less than 10pF. If the frequency of the feedback pole is much greater than the ideal closed-loop bandwidth (the nominal closed-loop bandwidth in the absence of CS), the pole has a negligible effect on stability, as only a small amount of phase shift is added. www.ti.com LMC6032, LMC6034 SNOS609D – NOVEMBER 1994 – REVISED FEBRUARY 2024 Copyright © 2024 Texas Instruments Incorporated Submit Document Feedback 11 Product Folder Links: LMC6032 LMC6034

However, if the feedback pole is less than approximately 6 to 10 times the ideal −3dB frequency, add a feedback capacitor, CF, between the output and the inverting input of the op amp. This condition can also be stated in terms of the amplifier low-frequency noise gain: To maintain stability, a feedback capacitor is probably needed if: R F R I N + 1 ≤ 6 × 2 π × G BW × R F × C S (2) where R F R I N + 1 is the amplifier low-frequency noise gain.

  • GBW is the amplifier gain bandwidth product. An amplifier low-frequency noise gain is represented by the following formula: R F R I N + 1 (3) regardless of whether the amplifier is being used in an inverting or noninverting mode. A feedback capacitor is more likely to be needed when the noise gain is low, the feedback resistor is large. or both. If the previous condition is met (indicating a feedback capacitor is probably be needed), and the noise gain is large enough that R F R I N + 1 ≥ 2 G BW × R F × C S , the following value of feedback capacitor is recommended: C F = C S

2 R F

(4) If R F R I N + 1 < 2 G BW × R F × C S , the feedback capacitor is: C F = C S GB W × R F (5) These capacitor values are usually significantly smaller than those given by the older, more conservative formula: C F = C S R I N R F (6) CS consists of the amplifier input capacitance plus any stray capacitance from the circuit board and socket. CF compensates for the pole caused by CS and the feedback resistor. Figure 6-2. General Operational Amplifier Circuit Using the smaller capacitors give much higher bandwidth with little degradation of transient response. Using a somewhat larger feedback capacitor can be necessary in any of the above cases to allow for unexpected stray capacitance, or to tolerate additional phase shifts in the loop, or excessive capacitive load, or to decrease the noise or bandwidth, or simply because the particular circuit implementation needs more feedback capacitance LMC6032, LMC6034 SNOS609D – NOVEMBER 1994 – REVISED FEBRUARY 2024 www.ti.com

to be sufficiently stable. For example, a PCB stray capacitance can be larger or smaller than the breadboard capacitance, so the actual preferred value for C F can be different from the one estimated using the breadboard. In most cases, check the value of CF on the actual circuit, starting with the computed value.

6.1.3 Capacitive Load Tolerance

Like many other op amps, the LMC603x can oscillate when applied a load that appears capacitive. The threshold of oscillation varies both with load and circuit gain. The configuration most sensitive to oscillation is a unity-gain follower. See also Section Typical Characteristics. The load capacitance interacts with the op amp output resistance to create an additional pole. If this pole frequency is sufficiently low, the op amp phase margin is degraded so that the amplifier is no longer stable at low gains. Figure 6-3 shows that the addition of a small resistor (50 Ω to 100Ω) in series with the op amp output, and a capacitor (5pF to 10pF) from inverting input to output pins, returns the phase margin to a safe value without interfering with lower-frequency circuit operation. Thus, larger values of capacitance can be tolerated without oscillation. In all cases, the output can ring heavily when the load capacitance is near the threshold for oscillation. Figure 6-3. Rx, Cx Improve Capacitive Load Tolerance Capacitive load driving capability is enhanced by using a pullup resistor to V + (Figure 6-4). Typically, a pullup resistor conducting 500 μA or more significantly improves capacitive load responses. The value of the pullup resistor must be determined based on the current sinking capability of the amplifier with respect to the desired output swing. The open-loop gain of the amplifier can also be affected by the pullup resistor (see Section 5.6). Figure 6-4.

6.1.4 Bias Current Testing

The test method of Figure 6-5 is appropriate for bench-testing bias current with reasonable accuracy. To understand the circuit operation, first close switch S2 momentarily. When S2 is opened, then: I b − = d V OU T dt × C 2 (7) Figure 6-5. Simple Input Bias Current Test Circuit A recommended capacitor for C2 is a 5pF or 10pF silver mica, NPO ceramic, or air-dielectric. When determining the magnitude of I b−, the leakage of the capacitor and socket must be taken into account. Leave switch S2 shorted most of the time, or else the dielectric absorption of the capacitor C2 can cause errors. Similarly, if S1 is shorted momentarily (while leaving S2 shorted), then: I b + = dV OU T dt × C 1 + C x (8) where Cx is the stray capacitance at the + input.

6.2 Typical Applications

Typical Single-Supply Applications Additional single-supply applications ideas are found in the LM358 data sheet. The LMC603x is pin-for-pin compatible with the LM358 and offers greater bandwidth and input resistance over the LM358. These features can improve the performance of many existing single-supply applications. Be aware, however, the supply voltage range of the LMC603x is smaller than that of the LM358. Figure 6-6. Instrumentation Amplifier If R1 = R5, R3 = R6, and R4 = R7, then AV = 100 for circuit shown. Use low-drift resistors for good CMRR performance over temperature. Matching of R3 to R6 and R4 to R7 affects CMRR. Gain is adjusted through R2. CMRR is adjusted through R7. An improved circuit can be designed using the RES11A-Q1, low-drift, precision, matched resistor pairs. Figure 6-7 shows how a precise gain of 99 is easily implemented. The capacitors are optional and are be used to improve noise performance, if needed. RES11A00-Q1 10k 10k IN IN+ LMC603x RES11A90-Q1 REF OUTLMC603x LMC603x C3 C1 C4 Figure 6-7.

6.3 Layout

6.3.1 Layout Guidelines

6.3.1.1 Printed Circuit Board Layout for High-Impedance Work

Generally, any circuit that operates with less than 1000pA of leakage current requires special layout of the printed circuit board (PCB). To take advantage of the ultra-low bias current of the LMC603x, typically less than 40fA, an excellent layout is essential. Fortunately, the techniques for obtaining low leakages are quite simple. Foremost, do not ignore the surface leakage of the PCB, even though the leakage can sometimes appear acceptably low, because under conditions of high humidity or dust or contamination, the surface leakage can be appreciable. To minimize the effect of any surface leakage, lay out a ring of foil completely surrounding the LMC603x inputs and the terminals of capacitors, diodes, conductors, resistors, relay terminals, and so on, connected to the op amp inputs. See Figure 6-16. To have a significant effect, place guard rings on both the top and bottom of the PCB. This PCB foil must then be connected to a voltage which is at the same voltage as the amplifier inputs, since no leakage current can flow between two points at the same potential. For example, a PCB trace-to-pad resistance of 10 12Ω, which is normally considered a very large resistance, can leak 5pA if the trace were a 5V bus adjacent to the pad of an input. This causes a 100 times degradation from the LMC603x actual performance. However, if a guard ring is held within 5mV of the inputs, then even a resistance of 10 11Ω causes only 50fA of leakage current, or perhaps a minor (2:1) degradation of the amplifier performance. See Figure 6-17, Figure 6-18, Figure 6-19 for typical connections of guard rings for standard op amp configurations. If both inputs are active and at high impedance, the guard can be tied to ground and still provide some protection; see Figure 6-20. Figure 6-16. Example of Guard Ring in PCB Layout Figure 6-17.

(2) Material type: When designated, preproduction parts are prototypes/experimental devices, and are not yet approved or released for full production. Testing and final process, including without limitation quality assurance, reliability performance testing, and/or process qualification, may not yet be complete, and this item is subject to further changes or possible discontinuation. If available for ordering, purchases will be subject to an additional waiver at checkout, and are intended for early internal evaluation purposes only. These items are sold without warranties of any kind. (3) RoHS values: Yes, No, RoHS Exempt. See the TI RoHS Statement for additional information and value definition. (4) Lead finish/Ball material: Parts may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width. (5) MSL rating/Peak reflow: The moisture sensitivity level ratings and peak solder (reflow) temperatures. In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown. Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board. Addendum-Page 1

www.ti.com 5-Mar-2026 (6) Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part. Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two combined represent the entire part marking for that device.
