## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of amplifier channel A. Rail-to-rail output, typical short-circuit current 130mA, output swing to within 25mV of rail with RL=2kΩ. |
| 2 | -INA | input | Inverting input of amplifier channel A. High-impedance CMOS input, input bias current typ 10pA, common-mode range -0.1V to +5.6V (Vs=5.5V). |
| 3 | +INA | input | Noninverting input of amplifier channel A. High-impedance CMOS input, rail-to-rail input, common-mode range -0.1V to +5.6V (Vs=5.5V). |
| 4 | V+ | power_in | Positive (highest) power supply pin. Operating range 2.5V to 5.5V single-supply (or ±1.25V to ±2.75V dual). Bypass with 0.1uF close to the pin. |
| 5 | +INB | input | Noninverting input of amplifier channel B. High-impedance CMOS input, rail-to-rail input, common-mode range -0.1V to +5.6V (Vs=5.5V). |
| 6 | -INB | input | Inverting input of amplifier channel B. High-impedance CMOS input, input bias current typ 10pA. |
| 7 | OUTB | output | Output of amplifier channel B. Rail-to-rail output, drives 2kΩ or 10kΩ loads to near supply rails. |
| 8 | OUTC | output | Output of amplifier channel C. Rail-to-rail output, typical short-circuit current 130mA. |
| 9 | -INC | input | Inverting input of amplifier channel C. High-impedance CMOS input, input bias current typ 10pA. |
| 10 | +INC | input | Noninverting input of amplifier channel C. Rail-to-rail input, common-mode range -0.1V to +5.6V (Vs=5.5V). |
| 11 | V- | power_in | Negative (lowest) power supply pin. Tie to GND for single-supply operation, or to negative rail for dual-supply. Bypass with 0.1uF close to the pin. |
| 12 | +IND | input | Noninverting input of amplifier channel D. Rail-to-rail input, common-mode range -0.1V to +5.6V (Vs=5.5V). |
| 13 | -IND | input | Inverting input of amplifier channel D. High-impedance CMOS input, input bias current typ 10pA. |
| 14 | OUTD | output | Output of amplifier channel D. Rail-to-rail output, drives 2kΩ or 10kΩ loads to near supply rails. |
