AD8531ARTZ

UMW · Operational Amplifier · SOT-23-5

AD8531ARTZ from UMW, in a SOT-23-5. 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 OUT A output Output of amplifier A, which the datasheet rates for ±250 mA output drive current.
2 V- power_in Negative supply rail; the part is specified for a 2.7 V to 6 V single supply, with 7 V as the absolute maximum supply voltage.
3 +IN A input Non-inverting input of amplifier A; the input voltage range spans GND to VS (rail-to-rail input).
4 -IN A input Inverting input of amplifier A; the input voltage range spans GND to VS, with a ±6 V differential input limit (±VS for supplies below 6 V).
5 V+ power_in Positive supply rail; the part operates from 2.7 V to 6 V, with 7 V as the absolute maximum supply voltage.
