DESCRIPTION

1.6V, 1µA Precision Rail-to-Rail Input and Output Op Amps The LT ®6003/LT6004/LT6005 are single/dual/quad op amps designed to maximize battery life and performance for portable applications. These ampliﬁ ers operate on sup- plies as low as 1.6V and are fully speciﬁ ed and guaranteed over temperature on 1.8V, 5V and ±8V supplies while only drawing 1µA maximum quiescent current. The ultralow supply current and low operating voltage are combined with excellent ampliﬁ er speciﬁ cations; input offset voltage of 500µV maximum with a typical drift of only 1µV/°C, input bias current of 90pA maximum, open loop gain of 100,000 and the ability to drive 500pF capaci- tive loads, making the LT6003/LT6004/LT6005 ampliﬁ ers ideal when excellent performance is required in battery powered applications. The single LT6003 is available in the 5-pin TSOT-23 and tiny 2mm × 2mm DFN packages. The dual LT6004 is available in the 8-pin MSOP and 3mm × 3mm DFN packages. The quad LT6005 is available in the 16-pin TSSOP and 5mm × 3mm DFN packages. These devices are speciﬁ ed over the com- mercial, industrial and automotive temperature ranges. ■ Wide Supply Range: 1.6V to 16V ■ Low Supply Current: 1µA/Ampliﬁ er Max ■ Low Input Bias Current: 90pA Max ■ Low Input Offset Voltage: 500µV Max ■ Low Input Offset Voltage Drift: 1µV/°C ■ CMRR: 100dB ■ PSRR: 95dB ■ A VOL Driving 20kΩ Load: 100,000 Min ■ Capacitive Load Handling: 500pF ■ Speciﬁ ed from –40°C to 125°C ■ Tiny 2mm × 2mm DFN Package ■ Portable Gas Monitors ■ Battery- or Solar-Powered Systems ■ Low Voltage Signal Processing ■ Micropower Active Filters TYPICAL APPLICATION Micropower Oxygen Sensor OXYGEN SENSOR CITY TECHNOLOGY 4OX(2) www.citytech.com 100k 100k VOUT = 1V IN AIR ISUPPLY = 0.95µA 10M 1.6V LT6003

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: A heat sink may be required to keep the junction temperature below absolute maximum. This depends on the power supply voltage and how many ampliﬁ ers are shorted. The θ JA specﬁ ed for the DC, DD and DHC packages is with minimal PCB heat spreading metal. Using expanded metal area on all layers of a board reduces this value. Note 3: The LT6003C/LT6004C/LT6005C and LT6003I/LT6004I/LT6005I are guaranteed functional over the temperature range of –40°C to 85°C. The LT6003H/LT6004H/LT6005H are guaranteed functional over the operating temperature range of –40°C to 125°C. Note 4: The LT6003C/LT6004C/LT6005C are guaranteed to meet speciﬁ ed performance from 0°C to 70°C. The LT6003C/LT6004C/LT6005C are designed, characterized and expected to meet speciﬁ ed performance from –40°C to 85°C but are not tested or QA sampled at these temperatures. The LT6003I/LT6004I/LT6005I are guaranteed to meet speciﬁ ed performance from –40°C to 85°C. The LT6003H/LT6004H/LT6005H are guaranteed to meet speciﬁ ed performance from –40°C to 125°C. Note 5: This parameter is not 100% tested. Note 6: Output voltage swings are measured between the output and power supply rails. Note 7: Limits are guaranteed by correlation to V S = 5V tests. Note 8: Limits are guaranteed by correlation to VS = 1.8V tests Note 9: Limits are guaranteed by correlation to VS = ±8V tests Note 10: Full-power bandwidth is calculated from the slew rate: FPBW = SR/πV P-P.

The positive supply of the LT6003/LT6004/LT6005 should be bypassed with a small capacitor (about 0.01μF) within an inch of the pin. When driving heavy loads, an additional 4.7μF electrolytic capacitor should be used. When using split supplies, the same is true for the negative supply pin. Rail-to-Rail Characteristics The LT6003/LT6004/LT6005 are fully functional for an input signal range from the negative supply to the positive sup- ply. Figure 1 shows a simpliﬁ ed schematic of the ampliﬁ er. The input stage consists of two differential ampliﬁ ers, a PNP stage Q3/Q6 and an NPN stage Q4/ Q5 that are active over different ranges of the input common mode voltage. The PNP stage is active for common mode voltages, V CM, between the negative supply to approximately 0.9V below the positive supply. As VCM moves closer towards the positive supply, the transistor Q7 will steer Q2’s tail current to the current mirror Q8/Q9, activating the NPN differential pair. The PNP pair becomes inactive for the rest of the input common mode voltage range up to the positive supply. The second stage is a folded cascode and current mir- ror that converts the input stage differential signals into a single ended output. Capacitor C1 reduces the unity cross frequency and improves the frequency stability without degrading the gain bandwidth of the ampliﬁ er. The complementary drive generator supplies current to the output transistors that swing from rail to rail. Input Input bias current (I B) is minimized with cancellation circuitry on both input stages. The cancellation circuitry remains active when V CM is more than 300mV from either rail. As VCM approaches V– the cancellation circuitry turns off and IB is determined by the tail current of Q2 and the beta of the PNP input transistors. As VCM approaches V+ devices in the cancellation circuitry saturate causing IB to increase (in the nanoamp range). Input offset voltage errors due to I B can be minimized by equalizing the noninverting and inverting source impedances. The input offset voltage changes depending on which input stage is active; input offset voltage is trimmed on both input stages, and is guaranteed to be 500μV max in the PNP stage. By trimming the input offset voltage of both input stages, the input offset voltage shift over the entire common mode range (CMRR) is typically 160μV, maintain- ing the precision characteristics of the ampliﬁ er. The input stage of the LT6003/LT6004/LT6005 incorpo- rates phase reversal protection to prevent wrong polarity outputs from occurring when the inputs are driven up to 9V below the negative rail. 600k protective resistors are included in the input leads so that current does not become excessive when the inputs are forced below V – or when a large differential signal is applied. Input current should be limited to 10mA when the inputs are driven above the positive rail. Output The output of the LT6003/LT6004/LT6005 is guaranteed to swing within 100mV of the positive rail and 50mV of the negative rail with no load, over the industrial temperature range. The LT6003/LT6004/LT6005 can typically source 8mA on a single 5V supply. Sourcing current is reduced to 5mA on a single 1.8V supply as noted in the electrical characteristics. However, when sourcing more than 250μA with an output load impedance greater than 20kΩ, a 1μF capacitor in series with a 2k resistor should be placed from the output to ground to insure stability. The normally reverse-biased substrate diode from the output to V – will cause unlimited currents to ﬂ ow when the output is forced below V –. If the current is transient and limited to 100mA, no damage will occur.

Gain for various loads shows the details. the output is on either rail. no difference, the outputs of A3 and A4 will be near zero. comparator output (wired in OR gate fashion) falls low. ampliﬁ er and comparator functions. Figure 2. Start-Up Characteristics
