OPA333AIDR

UMW · Precision Op Amps · SOP-8

OPA333AIDR from UMW, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection; can be left floating.
2 -IN input Inverting input; common-mode voltage range (V−) − 0.1 V to (V+) + 0.1 V.
3 +IN input Noninverting input; common-mode voltage range (V−) − 0.1 V to (V+) + 0.1 V.
4 V- power_in Negative (lowest) power supply; supply voltage range 1.8 V to 5.5 V.
5 NC unconnected No internal connection; can be left floating.
6 OUT output Output; rail-to-rail output swing within 50 mV of rails at RL = 10 kΩ.
7 V+ power_in Positive (highest) power supply; supply voltage range 1.8 V to 5.5 V.
8 NC unconnected No internal connection; can be left floating.
