MC33171DT from STMicroelectronics, in a SOP-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 1 | passive | Offset null terminal for input offset voltage trim, connected with Offset Null 2 across a 10 kΩ potentiometer whose wiper goes to VCC-. |
| 2 | Inverting Input | input | Inverting input; input voltage must not exceed the magnitude of VCC and common-mode range is VCC- to (VCC+ - 1.8 V) typical at 25°C. |
| 3 | Non-inverting Input | input | Non-inverting input; input voltage must not exceed the magnitude of VCC and common-mode range is VCC- to (VCC+ - 1.8 V) typical at 25°C. |
| 4 | VCC- | power_in | Negative supply (ground in single-supply use); total supply range is ±2 V to ±22 V (+4 V to +44 V single supply). |
| 5 | Offset Null 2 | passive | Offset null terminal for input offset voltage trim, connected with Offset Null 1 across a 10 kΩ potentiometer whose wiper goes to VCC-. |
| 6 | Output | output | Op-amp output with short-circuit protection of indefinite duration and low-level output typically 100 mV from VCC-. |
| 7 | VCC+ | power_in | Positive supply; total supply range is ±2 V to ±22 V (+4 V to +44 V single supply), maximum ±22 V. |
| 8 | N.C. | unconnected | No internal connection. |
