OPA277M from HGSEMI, 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 Trim | passive | Input offset voltage trim pin for nulling the amplifier offset only; leave floating if not used. |
| 2 | -In | input | Inverting input of the operational amplifier. |
| 3 | +In | input | Noninverting input of the operational amplifier. |
| 4 | V- | power_in | Negative (lowest) power supply; the device operates from ±2 V to ±16 V (4 V to 32 V total span). |
| 5 | NC | unconnected | No internal connection; can be left floating. |
| 6 | Output | output | Amplifier output. |
| 7 | V+ | power_in | Positive (highest) power supply; the device operates from ±2 V to ±16 V (4 V to 32 V total span). |
| 8 | Offset Trim | passive | Input offset voltage trim pin for nulling the amplifier offset only; leave floating if not used. |
