## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Amplifier A output. Rail-to-rail CMOS output, capable of ~25 mA short-circuit current, VOH ~4.998 V and VOL ~1 mV with RL=100 kΩ at Vs=5 V. |
| 2 | -IN A | input | Amplifier A inverting input. High-impedance CMOS input; typical bias current 10 pA. Common-mode range extends from (V-)-0.1 V to (V+)+0.1 V. |
| 3 | +IN A | input | Amplifier A non-inverting input. High-impedance rail-to-rail CMOS input; input-diode-clamped to the supply rails (limit external current to ≤10 mA if driven beyond rails). |
| 4 | V+ | power_in | Positive supply. Operating range +2.5 V to +5.5 V (single-supply) or ±1.25 V to ±2.75 V (dual-supply). Absolute max V+ to V- = 7.0 V. Bypass with a 0.1 µF capacitor placed close to the supply pins. |
| 5 | +IN B | input | Amplifier B non-inverting input. High-impedance rail-to-rail CMOS input. |

| 10 | +IN C | input | Amplifier C non-inverting input. High-impedance rail-to-rail CMOS input. |
| 11 | V- | power_in | Negative supply / ground. Tied to GND in single-supply operation, or to a negative rail in dual-supply. Absolute max V+ to V- = 7.0 V. |
| 12 | +IN D | input | Amplifier D non-inverting input. High-impedance rail-to-rail CMOS input. |
| 13 | -IN D | input | Amplifier D inverting input. High-impedance CMOS input. |
