**DIOO** · Video Amplifiers · SOIC-14

DIO2501CS14 from DIOO, 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 | VCC | power_in | Video filter driver power supply; the Recommended Operating Conditions give the supply range for this pin. |
| 2 | VIN | power_in | Video filter driver input that feeds the 6th-order SD video filter. |
| 3 | -INR | input | Right channel negative input of the audio line driver, which sets the gain through the RIN/RFB network. |
| 4 | OUTR | output | Right channel output of the audio line driver, which is AC-coupled to the load. |
| 5 | EN | input | Enable input, active-low; it should be kept low until the supplies are up for pop-free power-up. |
| 6 | VSS | power_out | Negative voltage output generated by the charge pump, which must be decoupled with a low-ESR capacitor. |
| 7 | CN | passive | Charge pump flying capacitor negative terminal, connected to the flying capacitor. |
| 8 | CP | passive | Charge pump flying capacitor positive terminal, connected to the flying capacitor. |
| 9 | VDD | power_in | Audio line driver positive supply; the Recommended Operating Conditions give the supply range for this pin. |
| 10 | GND | power_in | Ground reference pin. |
| 11 | OUTL | output | Left channel output of the audio line driver, which is AC-coupled to the load. |
| 12 | -INL | input | Left channel negative input of the audio line driver, which sets the gain through the RIN/RFB network. |
| 13 | VOUT | output | Video filter driver output of the SD video filter. |
| 14 | GND | power_in | Ground reference pin. |
