OPA333AIM5

HGSEMI · Precision Op Amps · SOT-23-5

OPA333AIM5 from HGSEMI, 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 Amplifier output; the datasheet gives a short-circuit current of ±5 mA and a rail-to-rail swing of about 100 mV from each supply rail.
2 V- power_in Negative power supply (lowest potential); operating supply is 1.8 V to 5.5 V as (V+) − (V−), with an absolute maximum of 7 V.
3 +IN input Non-inverting input; common-mode range is (V-) − 0.1 V to (V+) + 0.1 V, and input current must be limited to 10 mA if the signal exceeds a supply rail by more than 0.3 V.
4 -IN input Inverting input; same limits as +IN, with common-mode range (V-) − 0.1 V to (V+) + 0.1 V and 10 mA input current limit when driven beyond the rails by more than 0.3 V.
5 V+ power_in Positive power supply (highest potential); operating supply is 1.8 V to 5.5 V, with an absolute maximum of 7 V.
