AD8646ARMZ from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Output of amplifier A; the datasheet specifies rail-to-rail output swing and a short-circuit output current of ±120 mA at VSY = 5 V.
2 -INA input Inverting input of amplifier A; the input voltage range is GND to VSY (common-mode range 0 V to 5 V at VSY = 5 V).
3 +INA input Non-inverting input of amplifier A; the input voltage range is GND to VSY (common-mode range 0 V to 5 V at VSY = 5 V).
4 V- power_in Negative supply pin; the device operates from a single supply of 2.7 V to 5.5 V, and the absolute maximum supply voltage is 6 V.
5 +INB input Non-inverting input of amplifier B; the input voltage range is GND to VSY (common-mode range 0 V to 5 V at VSY = 5 V).
6 -INB input Inverting input of amplifier B; the input voltage range is GND to VSY (common-mode range 0 V to 5 V at VSY = 5 V).
7 OUTB output Output of amplifier B; the datasheet specifies rail-to-rail output swing and a short-circuit output current of ±120 mA at VSY = 5 V.
8 V+ power_in Positive supply pin; the device operates from a single supply of 2.7 V to 5.5 V, and the absolute maximum supply voltage is 6 V.
