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

SN10503D from Texas Instruments, in a SOIC-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 | NC | unconnected | No internal connection. |
| 2 | NC | unconnected | No internal connection. |
| 3 | NC | unconnected | No internal connection. |
| 4 | VS+ | power_in | Positive supply; total supply is 2.7 V to 16 V single supply (absolute maximum 16.5 V). |
| 5 | 1IN+ | input | Channel 1 non-inverting input; common-mode range is VS- + 1.1 V to VS+ - 1.1 V. |
| 6 | 1IN- | input | Channel 1 inverting input; common-mode range is VS- + 1.1 V to VS+ - 1.1 V. |
| 7 | 1OUT | output | Channel 1 rail-to-rail output, typically 100 mA output drive. |
| 8 | 3OUT | output | Channel 3 rail-to-rail output, typically 100 mA output drive. |
| 9 | 3IN- | input | Channel 3 inverting input; common-mode range is VS- + 1.1 V to VS+ - 1.1 V. |
| 10 | 3IN+ | input | Channel 3 non-inverting input; common-mode range is VS- + 1.1 V to VS+ - 1.1 V. |
| 11 | VS- | power_in | Negative supply (ground in single-supply operation); dual supply is ±1.35 V to ±8 V. |
| 12 | 2IN+ | input | Channel 2 non-inverting input; common-mode range is VS- + 1.1 V to VS+ - 1.1 V. |
| 13 | 2IN- | input | Channel 2 inverting input; common-mode range is VS- + 1.1 V to VS+ - 1.1 V. |
| 14 | 2OUT | output | Channel 2 rail-to-rail output, typically 100 mA output drive. |
