OPA27GU from Texas Instruments, in a SOIC-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 Trim | passive | Offset voltage trim terminal; apply potentiometer (1kΩ to 1MΩ range, 10kΩ recommended) between pins 1 and 8 to adjust input offset voltage with ±4mV to ±280µV typical trim range. |
| 2 | -In | input | Inverting input terminal; maximum input voltage ±VCC; differential input voltage limited to ±0.7V by back-to-back diode protection; common-mode input range ±11V to ±12.3V. |
| 3 | +In | input | Non-inverting input terminal; maximum input voltage ±VCC; differential input voltage limited to ±0.7V by back-to-back diode protection; common-mode input range ±11V to ±12.3V. |
| 4 | -VCC | power_in | Negative supply voltage terminal; operating range ±4V to ±22V with rated performance at ±15V; quiescent current 3.3mA to 5.7mA. |
| 5 | NC | unconnected | No connection; internal standoff pin for SOIC package. |
| 6 | Output | output | Output terminal; rated output voltage ±12V to ±13.8V at RL≥2kΩ, ±10V to ±12.8V at RL≥600Ω; open-loop output resistance 70Ω; short-circuit current 25mA to 60mA. |
| 7 | +VCC | power_in | Positive supply voltage terminal; operating range ±4V to ±22V with rated performance at ±15V; quiescent current 3.3mA to 5.7mA. |
| 8 | Offset Trim | passive | Offset voltage trim terminal; apply potentiometer (1kΩ to 1MΩ range, 10kΩ recommended) between pins 1 and 8 to adjust input offset voltage with ±4mV to ±280µV typical trim range. |
