## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail output stage capable of ~70 mA drive (1 V drop), short-circuit current typ 130 mA. |
| 2 | -INA | input | Amplifier A inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V; typ input bias current 0.3 pA at 27 °C. |
| 3 | +INA | input | Amplifier A non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V. |
| 4 | +Vs | power_in | Positive supply rail. Single-supply 2.2 V to 5.5 V (or ±1.1 V to ±2.75 V split). Bypass locally with 100 nF ceramic. Absolute max V+−V− = 7 V. |
| 5 | +INB | input | Amplifier B non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V. |
| 6 | -INB | input | Amplifier B inverting input. Rail-to-rail input; typ input bias current 0.3 pA at 27 °C. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage capable of ~70 mA drive (1 V drop). |
| 8 | OUTC | output | Amplifier C output. Rail-to-rail output stage capable of ~70 mA drive (1 V drop). |
| 9 | -INC | input | Amplifier C inverting input. Rail-to-rail input; typ input bias current 0.3 pA at 27 °C. |
| 10 | +INC | input | Amplifier C non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V. |
| 11 | -Vs | power_in | Negative supply rail / ground for single-supply operation. Tie to GND for single-supply use, or to the negative rail for split supplies. Absolute max V+−V− = 7 V. |
| 12 | +IND | input | Amplifier D non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V. |
| 13 | -IND | input | Amplifier D inverting input. Rail-to-rail input; typ input bias current 0.3 pA at 27 °C. |
| 14 | OUTD | output | Amplifier D output. Rail-to-rail output stage capable of ~70 mA drive (1 V drop). |
