OPA2172IDGK from Texas Instruments, in a VSSOP-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 | OUT A | output | Output of channel A; rail-to-rail output swinging 70-90 mV from supply rails at 10 kΩ load and ±36 V supply. |
| 2 | -IN A | input | Inverting input of channel A; common-mode input range (V-) - 0.1 V to (V+) - 2 V with ±0.2 mV typical input offset voltage. |
| 3 | +IN A | input | Noninverting input of channel A; common-mode input range (V-) - 0.1 V to (V+) - 2 V with ±8 pA typical input bias current. |
| 4 | V- | power_in | Negative (lowest) power supply; supports supply voltage range 4.5 to 36 V single supply (±2.25 to ±18 V dual supply), maximum supply differential 40 V. |
| 5 | +IN B | input | Noninverting input of channel B; common-mode input range (V-) - 0.1 V to (V+) - 2 V with ±8 pA typical input bias current. |
| 6 | -IN B | input | Inverting input of channel B; common-mode input range (V-) - 0.1 V to (V+) - 2 V with ±0.2 mV typical input offset voltage. |
| 7 | OUT B | output | Output of channel B; rail-to-rail output swinging 70-90 mV from supply rails at 10 kΩ load and ±36 V supply. |
| 8 | V+ | power_in | Positive (highest) power supply; supports supply voltage range 4.5 to 36 V single supply (±2.25 to ±18 V dual supply), maximum supply differential 40 V. |
