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. |
