OPA2171MDCUTEP from Texas Instruments, in a VSSOP-8-0.5mm. 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 | OUT A | output | Output of channel A, which swings to within 0.35 V of the rails (V-)+0.35 V to (V+)-0.35 V at RL = 10 kΩ and has a short-circuit current of +25/-35 mA. |
| 2 | -IN A | input | Inverting input of channel A; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V, and it can extend up to V+ with reduced performance. |
| 3 | +IN A | input | Noninverting input of channel A; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V, and it can extend up to V+ with reduced performance. |
| 4 | V- | power_in | Negative (lowest) power supply; the total supply voltage (V+ - V-) is specified from 4.5 V (±2.25 V) to 36 V (±18 V). |
| 5 | +IN B | input | Noninverting input of channel B; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V, and it can extend up to V+ with reduced performance. |
| 6 | -IN B | input | Inverting input of channel B; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V, and it can extend up to V+ with reduced performance. |
| 7 | OUT B | output | Output of channel B, which swings to within 0.35 V of the rails (V-)+0.35 V to (V+)-0.35 V at RL = 10 kΩ and has a short-circuit current of +25/-35 mA. |
| 8 | V+ | power_in | Positive (highest) power supply; the total supply voltage (V+ - V-) is specified from 4.5 V (±2.25 V) to 36 V (±18 V), with an absolute maximum supply of ±20 V. |
