DESCRIPTION

1.6V, 1µA Precision Rail-to-Rail Input and Output Op Amps The L T®6003/L T6004/L T6005 are single/dual/quad op amps designed to maximize battery life and performance for portable applications. These amplifiers operate on sup - plies as low as 1.6V and are fully specified 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 amplifier specifications; input offset voltage of 500µV maximum with a typical drift of only 2µV/°C, input bias current of 90pA maximum, open loop gain of 100,000 and the ability to drive 500pF capaci- tive loads, making the L T6003/L T6004/L T6005 amplifiers ideal when excellent performance is required in battery powered applications. The single L T6003 is available in the 5-pin TSOT-23 and tiny 2mm × 2mm DFN packages. The dual L T6004 is available in the 8-pin MSOP and 3mm × 3mm DFN packages. The quad L T6005 is available in the 16-pin SSOP and 5mm × 3mm DFN packages. These devices are specified over the com- mercial, industrial and automotive temperature ranges. n Wide Supply Range: 1.6V to 16V n Low Supply Current: 1µA/Amplifier Max n Low Input Bias Current: 90pA Max n Low Input Offset Voltage: 500µV Max n Low Input Offset Voltage Drift: 2µV/°C n CMRR: 100dB n PSRR: 95dB n AVOL Driving 20kΩ Load: 100,000 Min n Capacitive Load Handling: 500pF n Specified from –40°C to 125°C n Available in Tiny 2mm × 2mm DFN and Low Profile (1mm) ThinSOT™ Packages n Portable Gas Monitors n Battery- or Solar-Powered Systems n Low Voltage Signal Processing n Micropower Active Filters TYPICAL APPLICATION Micropower Oxygen Sensor OXYGEN SENSOR CITY TECHNOLOGY 4OX(2) www.citytech.com 100k 100k VOUT = 1V IN AIR ISUPPL Y = 0.95µA 10M 1.6V L T6003

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 amplifiers are shorted. The θ JA specified 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 L T6003C/L T6004C/L T6005C and L T6003I/L T6004I/L T6005I are guaranteed functional over the temperature range of –40°C to 85°C. The L T6003H/L T6004H/L T6005H are guaranteed functional over the operating temperature range of –40°C to 125°C. Note 4: The L T6003C/L T6004C/L T6005C are guaranteed to meet specified performance from 0°C to 70°C. The L T6003C/L T6004C/L T6005C are designed, characterized and expected to meet specified performance from –40°C to 85°C but are not tested or QA sampled at these temperatures. The L T6003I/L T6004I/L T6005I are guaranteed to meet specified performance from –40°C to 85°C. The L T6003H/L T6004H/L T6005H are guaranteed to meet specified 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/πVP-P. Note 11: Slew rate measured at VS = 1.8V , VOUT = 0.4V to 1.4V is used to guarantee by correlation the slew rate at VS = 5V , VOUT = 1V to 4V and the slew rate at VS = ±8V , VOUT = –5V to 5V .

The positive supply of the L T6003/L T6004/L T6005 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 L T6003/L T6004/L T6005 are fully functional for an input signal range from the negative supply to the positive sup- ply. Figure 1 shows a simplified schematic of the amplifier . The input stage consists of two differential amplifiers, 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 amplifier . 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 VCM 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 , maintaining the precision characteristics of the amplifier . The input stage of the L T6003/L T6004/L T6005 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 L T6003/L T6004/L T6005 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 L T6003/L T6004/L T6005 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 flow when the output is forced below V –. If the current is transient and limited to 100mA, no damage will occur .

Open-Loop 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. amplifier and comparator functions. Figure 2. Start-Up Characteristics
