OPA170AIDR 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 | NC | unconnected | No internal connection (can be left floating). |
| 2 | IN- | input | Negative (inverting) input of the op amp. |
| 3 | IN+ | input | Positive (noninverting) input of the op amp. |
| 4 | V- | power_in | Negative (lowest) power supply; supply range V+ to V- is 2.7 V to 36 V. |
| 5 | NC | unconnected | No internal connection (can be left floating). |
| 6 | OUT | output | Op amp output (rail-to-rail). |
| 7 | V+ | power_in | Positive (highest) power supply; supply range V+ to V- is 2.7 V to 36 V. |
| 8 | NC | unconnected | No internal connection (can be left floating). |
