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 | OUT A | output | Amplifier A output. Rail-to-rail output stage; typical output swing within 20mV of rails at RL=2kΩ, 7mV at RL=10kΩ. Short-circuit current ~110mA. |+| 2 | -IN A | input | Inverting input of amplifier A. High-impedance CMOS input, IB ~1pA typical. Input common-mode range -0.1V to +5.6V at Vs=5.5V; internally diode-clamped to supply rails (limit external drive to ±10mA beyond rails). |+| 3 | +IN A | input | Non-inverting input of amplifier A. High-impedance CMOS input, IB ~1pA typical, rail-to-rail input common-mode range. |+| 4 | V- | power_in | Negative supply rail (or ground in single-supply operation). Total supply voltage V+ to V- range 2.5V to 5.5V (absolute max 7.0V). Place 0.1uF bypass capacitor close to the pin. |+| 5 | +IN B | input | Non-inverting input of amplifier B. High-impedance CMOS input, IB ~1pA typical, rail-to-rail input common-mode range. |+| 6 | -IN B | input | Inverting input of amplifier B.
