Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUTA | output | Output of amplifier A. Rail-to-rail output stage, can swing to within ~5mV of the supply rails at RL >= 100kOhm. Typical source/sink current ~84mA/75mA into 10Ohm to VS/2. |+| 2 | INA- | input | Inverting input of amplifier A. Rail-to-rail CMOS input; common-mode range extends from VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical. |+| 3 | INA+ | input | Non-inverting input of amplifier A. Rail-to-rail CMOS input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical; input offset voltage 3.5mV max at 25C. |+| 4 | VSS | power_in | Negative supply rail (or ground in single-supply operation). Absolute maximum VDD-VSS = 7.5V; operating supply 2.1V to 5.5V single-supply, or +/-1.05V to +/-2.75V dual-supply. Bypass with 0.1uF ceramic to VDD close to the pin. |+| 5 | INB+ | input | Non-inverting input of amplifier B. Rail-to-rail CMOS input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical. |+| 6 | INB- | input | Inverting input of amplifier B. Rail-to-rail CMOS input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical. |+| 7 | OUTB | output | Output of amplifier B. Rail-to-rail output stage, swings to within ~5mV of the supply rails at light loads. Typical source/sink current ~84mA/75mA into 10Ohm to VS/2. |+| 8 | VDD | power_in | Positive supply rail. Operating range 2.1V to 5.5V single-supply; absolute maximum VDD-VSS = 7.5V.
