**Texas Instruments** · Precision Op Amps · TSSOP-14

OPA4388IPWR from Texas Instruments, in a TSSOP-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 | Op-amp output, channel A. Rail-to-rail output stage, swings within a few mV of V+ and V-. |
| 2 | -IN A | input | Inverting input, channel A. True rail-to-rail input, common-mode range V- to V+. |
| 3 | +IN A | input | Noninverting input, channel A. True rail-to-rail input, common-mode range V- to V+. |
| 4 | V+ | power_in | Positive (highest) power supply. Single-supply 2.5 V to 5.5 V, or dual-supply ±1.25 V to ±2.75 V. Absolute max VS = (V+) - (V-) = 6 V. |
| 5 | +IN B | input | Noninverting input, channel B. True rail-to-rail input. |
| 6 | -IN B | input | Inverting input, channel B. True rail-to-rail input. |
| 7 | OUT B | output | Op-amp output, channel B. Rail-to-rail output stage. |
| 8 | OUT C | output | Op-amp output, channel C. Rail-to-rail output stage. |
| 9 | -IN C | input | Inverting input, channel C. True rail-to-rail input. |
| 10 | +IN C | input | Noninverting input, channel C. True rail-to-rail input. |
| 11 | V- | power_in | Negative (lowest) power supply. Tie to GND for single-supply operation, or to a negative rail for dual-supply operation (±1.25 V to ±2.75 V). |
| 12 | +IN D | input | Noninverting input, channel D. True rail-to-rail input. |
| 13 | -IN D | input | Inverting input, channel D. True rail-to-rail input. |
| 14 | OUT D | output | Op-amp output, channel D. Rail-to-rail output stage. |
