OPA177GS from Texas Instruments, in a SOP-8-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Offset Trim | passive | Offset voltage trim terminal. Connect a 14 kΩ potentiometer between pins 1 and 8 with the wiper to V+ to null residual input offset voltage. Leave open if trimming is not required (laser-trimmed factory offset is 25 µV max). |
| 2 | -In | input | Inverting analog input of the op amp. High-impedance input (differential mode 45 MΩ typ, common-mode 200 GΩ typ); common-mode input range ±13 V min at ±15 V supplies. |
| 3 | +In | input | Non-inverting analog input of the op amp. High-impedance input (differential mode 45 MΩ typ, common-mode 200 GΩ typ); common-mode input range ±13 V min at ±15 V supplies. |
| 4 | V- | power_in | Negative supply rail. Typically -15 V; absolute maximum supply voltage is ±22 V. Bypass to ground with a local ceramic capacitor. |
| 5 | NC | unconnected | No internal connection. Leave floating or optionally tie to ground; not connected to any internal circuitry. |
| 6 | Vo | output | Op amp output. Output voltage swing typically ±14 V with RL ≥ 10 kΩ at ±15 V supplies; open-loop output resistance ~60 Ω. Short-circuit protected (continuous). |
| 7 | V+ | power_in | Positive supply rail. Typically +15 V; absolute maximum supply voltage is ±22 V. Bypass to ground with a local ceramic capacitor. |
| 8 | Offset Trim | passive | Offset voltage trim terminal. Connect a 14 kΩ potentiometer between pins 1 and 8 with the wiper to V+ to null residual input offset voltage. Leave open if trimming is not required. |
