OPA4172AQPWRQ1 from Texas Instruments, in a TSSOP-14. 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 amplifier channel A; the datasheet states that a short-circuit to ground is continuous, one amplifier per package. |
| 2 | -IN A | input | Inverting input of amplifier channel A; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 3 | +IN A | input | Non-inverting input of amplifier channel A; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 4 | V+ | power_in | Positive (highest) power supply; single-supply operation is specified from 4.5 V to 36 V, and dual supply from ±2.25 V to ±18 V. |
| 5 | +IN B | input | Non-inverting input of amplifier channel B; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 6 | -IN B | input | Inverting input of amplifier channel B; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 7 | OUT B | output | Output of amplifier channel B; the datasheet states that a short-circuit to ground is continuous, one amplifier per package. |
| 8 | OUT C | output | Output of amplifier channel C; the datasheet states that a short-circuit to ground is continuous, one amplifier per package. |
| 9 | -IN C | input | Inverting input of amplifier channel C; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 10 | +IN C | input | Non-inverting input of amplifier channel C; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 11 | V- | power_in | Negative (lowest) power supply; for single-supply use this is the ground reference, and the input range extends 0.1 V below it. |
| 12 | +IN D | input | Non-inverting input of amplifier channel D; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 13 | -IN D | input | Inverting input of amplifier channel D; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V. |
| 14 | OUT D | output | Output of amplifier channel D; the datasheet states that a short-circuit to ground is continuous, one amplifier per package. |
