OPA4388ID from UMW, in a SOP-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 channel A; the datasheet specifies a continuous output short-circuit rating, with one amplifier per package short-circuited to ground. |
| 2 | -IN A | input | Inverting input of channel A; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 3 | +IN A | input | Noninverting input of channel A; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 4 | V+ | power_in | Positive (highest) power supply; single-supply operation is 2.5 V to 5.5 V (6 V absolute maximum) or dual-supply ±1.25 V to ±2.75 V. |
| 5 | +IN B | input | Noninverting input of channel B; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 6 | -IN B | input | Inverting input of channel B; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 7 | OUT B | output | Output of channel B; the datasheet specifies a continuous output short-circuit rating, with one amplifier per package short-circuited to ground. |
| 8 | OUT C | output | Output of channel C; the datasheet specifies a continuous output short-circuit rating, with one amplifier per package short-circuited to ground. |
| 9 | -IN C | input | Inverting input of channel C; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 10 | +IN C | input | Noninverting input of channel C; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 11 | V- | power_in | Negative (lowest) power supply; the device runs single-supply from 2.5 V to 5.5 V or dual-supply from ±1.25 V to ±2.75 V. |
| 12 | +IN D | input | Noninverting input of channel D; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 13 | -IN D | input | Inverting input of channel D; signal input pins are rated from (V-) - 0.5 V to (V+) + 0.5 V in common mode per the absolute maximum ratings. |
| 14 | OUT D | output | Output of channel D; the datasheet specifies a continuous output short-circuit rating, with one amplifier per package short-circuited to ground. |
