OPA2171AIDGKR from Texas Instruments, in a VSSOP-8. 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 | OUT A | output | Output of amplifier A; voltage swing range from (V-) + 0.35V to (V+) - 0.35V at RL = 10kΩ. |
| 2 | -IN A | input | Inverting input terminal of amplifier A; common mode voltage range (V-) - 0.1V to (V+) - 2V. |
| 3 | +IN A | input | Non-inverting input terminal of amplifier A; common mode voltage range (V-) - 0.1V to (V+) - 2V. |
| 4 | V- | power_in | Negative (lowest) power supply; operating voltage range 2.7V to 36V. |
| 5 | +IN B | input | Non-inverting input terminal of amplifier B; common mode voltage range (V-) - 0.1V to (V+) - 2V. |
| 6 | -IN B | input | Inverting input terminal of amplifier B; common mode voltage range (V-) - 0.1V to (V+) - 2V. |
| 7 | OUT B | output | Output of amplifier B; voltage swing range from (V-) + 0.35V to (V+) - 0.35V at RL = 10kΩ. |
| 8 | V+ | power_in | Positive (highest) power supply; operating voltage range 2.7V to 36V. |
