OPA305ASOT235

analogysemi · Operational Amplifier · SOT-23-5

OPA305ASOT235 from analogysemi, 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 output Output of the amplifier.
2 V- power_in Negative (lowest) power supply. Operating voltage range is split ±1.35V to ±18V or single supply 2.7V to 36V.
3 +IN input Positive (non-inverting) input. Input range can extend up to V+ (input range is specified up to (V+) - 2V, extendable to V+).
4 -IN input Negative (inverting) input.
5 V+ power_in Positive (highest) power supply. Absolute maximum single-supply voltage is 40V.
