3 Description
The TLV07 is a 36-V, single-supply, low-noise, precision operational amplifier (op amp) manufactured using TI’s e-trim™ operational amplifier technology. The e-trim technology is a TI proprietary method of trimming internal device parameters during either wafer probing or final testing. Each amplifiers' input offset voltage is trimmed in production to obtain a low offset voltage of 100 µV (maximum). The TLV07 offers outstanding dc precision and ac performance, including rail-to-rail output, low offset voltage (±100 µV, maximum) and 1-MHz bandwidth. The TLV07 is stable at G = 1 with capacitive loads up to 200 pF. The input can operate 100 mV below the negative rail and within 2 V of the positive rail. This wide input voltage range, combined with a high CMRR of 120 dB, make the TLV07 well-suited when operated in the non-inverting configuration. The TLV07 op amp is specified from –40°C to +125°C.

7.1 Overview
The TLV07 operational amplifier provides high overall performance, making the device suitable for many general- purpose applications. The excellent offset drift of only 0.9 μV/°C provides excellent stability over the entire temperature range. In addition, the device offers very good overall performance with high CMRR, PSRR, and AOL.

7.3.2 Electrical Overstress
Designers often ask questions about the capability of an operational amplifier to withstand electrical overstress. characteristics of the particular semiconductor fabrication process and specific circuits connected to the pin. ESD events before and during product assembly. during normal circuit operation. Figure 1. Equivalent Internal ESD Circuitry Relative to a Typical Circuit Application protection circuitry is then dissipated as heat.
ADVANCE□INFORMATION TLV07 www.ti.com SBOS832 –JULY 2017 Product Folder Links: TLV07 Submit Documentation FeedbackCopyright © 2017, Texas Instruments Incorporated Feature Description (continued) When an ESD voltage develops across two or more amplifier device pins, current flows through one or more steering diodes. Depending on the path that the current takes, the absorption device can activate. The absorption device has a trigger, or threshold voltage, that is above the normal operating voltage of the TLV07, but below the device breakdown voltage level. When this threshold is exceeded, the absorption device quickly activates and clamps the voltage across the supply rails to a safe level. When the operational amplifier connects into a circuit (see Figure 1), the ESD protection components are intended to remain inactive and do not become involved in the application circuit operation. However, circumstances may arise where an applied voltage exceeds the operating voltage range of a given pin. If this condition occurs, there is a risk that some internal ESD protection circuits can turn on and conduct current. Any such current flow occurs through steering-diode paths and rarely involves the absorption device. Figure 1 shows a specific example where the input voltage (VIN) exceeds the positive supply voltage (V+) by 500 mV or more. Much of what happens in the circuit depends on the supply characteristics. If V+ can sink the current, one of the upper input steering diodes conducts and directs current to V+. Excessively high current levels can flow with increasingly higher VIN. As a result, the data sheet specifications recommend that applications limit the input current to 10 mA. If the supply is not capable of sinking the current, VIN sources current to the operational amplifier and becomes the source of positive supply voltage. The danger in this case is that the voltage can rise to levels that exceed the operational amplifier absolute maximum ratings. Another common question involves what happens to the amplifier if an input signal is applied to the input when the power supplies (V+ or V–) are at 0 V. This question depends on the supply characteristic when at 0 V, or at a level below the input signal amplitude. If the supplies appear as high impedance, then the input source supplies the operational amplifier current through the current-steering diodes. This state is not a normal bias condition; most likely, the amplifier does not operate normally. If the supplies are low impedance, then the current through the steering diodes can become quite high. The current level depends on the ability of the input source to deliver current, and any resistance in the input path. If there is any uncertainty about the ability of the supply to absorb this current, add external Zener diodes to the supply pins; see Figure 1. Select the Zener voltage so that the diode does not turn on during normal operation. However, the Zener voltage must be low enough so that the Zener diode conducts if the supply pin begins to rise above the safe-operating, supply-voltage level. The TLV07 input pins are protected from excessive differential voltage with back-to-back diodes; see Figure 1. In most circuit applications, the input protection circuitry has no effect. However, in low-gain or G = 1 circuits, fast- ramping input signals can forward-bias these diodes because the output of the amplifier cannot respond rapidly enough to the input ramp. If the input signal is fast enough to create this forward-bias condition, limit the input signal current to 10 mA or less. If the input signal current is not inherently limited, use an input series resistor to limit the input signal current.

9 Power Supply Recommendations
The TLV07 is specified for operation from 2.7 V to 36 V (±2.25 V to ±18 V); many specifications apply from –40°C to +125°C. Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in . CAUTION Supply voltages larger than 40 V can permanently damage the device; see Absolute Maximum Ratings. Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high- impedance power supplies. For more detailed information on bypass capacitor placement, see Layout Guidelines.

10 Layout
10.1 Layout Guidelines
For best operational performance of the device, use good printed-circuit board (PCB) layout practices, including:
- Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the operational amplifier itself. Bypass capacitors reduce the coupled noise by providing low-impedance power sources local to the analog circuitry. – Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for single- supply applications.
- Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective methods of noise suppression. One or more layers on multilayer PCBs are typically devoted to ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Take care to physically separate digital and analog grounds, paying attention to the flow of the ground current.
- In order to reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If these traces cannot be kept separate, crossing the sensitive trace perpendicularly is much better than in parallel with the noisy trace.
- Place the external components as close to the device as possible. As shown in Figure 5, keeping RF and RG close to the inverting input minimizes parasitic capacitance.
- Keep the length of input traces as short as possible. Always remember that the input traces are the most sensitive part of the circuit.
- Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce leakage currents from nearby traces that are at different potentials.
