OPA501BSOT235

analogysemi · Operational Amplifier · SOT23-5

OPA501BSOT235 from analogysemi, in a SOT23-5. 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 output Amplifier output, swinging between the V- and V+ supply rails.
2 V- power_in Negative (lowest) power supply pin, the reference for signal input and output limits.
3 +IN input Positive (non-inverting) input.
4 -IN input Negative (inverting) input.
5 V+ power_in Positive (highest) power supply; operating voltage range is 1.6V to 5.5V.
