OPA4172IDR from Texas Instruments, in a SOIC-14. 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 channel A. Rail-to-rail output, capable of high output current drive. |
| 2 | -IN A | input | Inverting input, amplifier channel A. Input common-mode range extends from (V-) - 0.1 V to (V+) + 2 V (normal operation). |
| 3 | +IN A | input | Noninverting input, amplifier channel A. |
| 4 | V+ | power_in | Positive (highest) power supply. Single-supply +4.5 V to +36 V, or split-supply ±2.25 V to ±18 V. Bypass to V- with a low-ESR ceramic capacitor. |
| 5 | +IN B | input | Noninverting input, amplifier channel B. |
| 6 | -IN B | input | Inverting input, amplifier channel B. |
| 7 | OUT B | output | Output of amplifier channel B. Rail-to-rail output. |
| 8 | OUT C | output | Output of amplifier channel C. Rail-to-rail output. |
| 9 | -IN C | input | Inverting input, amplifier channel C. |
| 10 | +IN C | input | Noninverting input, amplifier channel C. |
| 11 | V- | power_in | Negative (lowest) power supply. Ground for single-supply operation, or negative rail for split-supply operation (down to -18 V). |
| 12 | +IN D | input | Noninverting input, amplifier channel D. |
| 13 | -IN D | input | Inverting input, amplifier channel D. |
| 14 | OUT D | output | Output of amplifier channel D. Rail-to-rail output. |
