MC33171DR2G

onsemi · Operational Amplifier · SO-8

MC33171DR2G from onsemi, in a SO-8. 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 Offset Null passive Offset null pin for the MC33171 only; a 10 kΩ potentiometer gives an offset nulling range of approximately ±80 mV.
2 Inv. Input input Inverting input; the input common mode voltage range extends down to VEE, and input voltages must not exceed the VCC or VEE supply magnitudes (Note 1, maximum ratings).
3 Noninv. Input input Non-inverting input; the input common mode voltage range extends down to VEE, and input voltages must not exceed the VCC or VEE supply magnitudes (Note 1, maximum ratings).
4 VEE power_in Negative supply rail; the device operates from 3.0 V to 44 V single supply or ±1.5 V to ±22 V split supplies, with a maximum supply of ±22 V.
5 Offset Null passive Second offset null pin for the MC33171 only; a 10 kΩ potentiometer gives an offset nulling range of approximately ±80 mV.
6 Output output Amplifier output, current limited and protected against a direct short to ground; it can sink at least 15 mA, typically to within about VEE +1.8 V.
7 VCC power_in Positive supply rail; the device operates from 3.0 V to 44 V single supply or ±1.5 V to ±22 V split supplies, with a maximum supply of ±22 V.
8 NC unconnected No connection, as shown on the SO-8 pin diagram.
