OPA171AIDR from Texas Instruments, in a SO-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 circuit connection; can be left floating |
| 2 | -IN | input | Inverting input; input common mode voltage range from (V-) - 0.1 V to (V+) - 2 V; input bias current ±8 pA typical |
| 3 | +IN | input | Non-inverting input; input common mode voltage range from (V-) - 0.1 V to (V+) - 2 V; input bias current ±8 pA typical |
| 4 | V- | power_in | Negative (lowest) power supply; rated voltage range 2.7 V to 36 V (or ±1.35 V to ±18 V) |
| 5 | NC | unconnected | No internal circuit connection; can be left floating |
| 6 | OUT | output | Output; voltage can swing within ±0.35 V of supply rails; maximum short circuit current +25 mA (source) / -35 mA (sink) at +25°C |
| 7 | V+ | power_in | Positive (highest) power supply; rated voltage range 2.7 V to 36 V (or ±1.35 V to ±18 V) |
| 8 | NC | unconnected | No internal circuit connection; can be left floating |
