**Texas Instruments** · Video Amplifiers · TSSOP-14

OPA3355EA 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 | ENABLE A | input | Amplifier power-down control for channel A: low disables the amplifier, high gives normal operation, and the pin must be driven. |
| 2 | ENABLE B | input | Amplifier power-down control for channel B: low disables the amplifier, high gives normal operation, and the pin must be driven. |
| 3 | ENABLE C | input | Amplifier power-down control for channel C: low disables the amplifier, high gives normal operation, and the pin must be driven. |
| 4 | V+ | power_in | Positive power supply pin. |
| 5 | +IN A | input | Noninverting input pin for channel A. |
| 6 | -IN A | input | Inverting input pin for channel A. |
| 7 | OUT A | output | Output pin for channel A. |
| 8 | OUT B | output | Output pin for channel B. |
| 9 | -IN B | input | Inverting input pin for channel B. |
| 10 | +IN B | input | Noninverting input pin for channel B. |
| 11 | V- | power_in | Negative power supply pin. |
| 12 | +IN C | input | Noninverting input pin for channel C. |
| 13 | -IN C | input | Inverting input pin for channel C. |
| 14 | OUT C | output | Output pin for channel C. |
