# D1671

**Silicore(芯谷)** · Video Amplifiers · SOT-23-6

D1671 from Silicore(芯谷), in a SOT-23-6. 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 | PS | input | Power-save control input: H (2.0V to Vcc) turns the amplifier off (standby, Icc 1µA max), L (0.5V max) or open turns it on. |
| 2 | OUT | output | Video signal output from the 75Ω driver, with a typical DC output voltage of 0.3V (0.15 to 0.45V). |
| 3 | SAG | passive | SAG correction terminal, connected to the output stage through a 500Ω resistor and the feedback path. |
| 4 | IN | input | Video signal input to the 4th-order low-pass filter, with a typical input bias voltage of 1.2V. |
| 5 | GND | power_in | Ground terminal. |
| 6 | VCC | power_in | Power supply terminal, recommended 2.8 to 5.5V (absolute maximum 7V). |
