MC33171DT

STMicroelectronics · Operational Amplifier · SOP-8

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.
