# XC7468

**Si Change** · Analog To Digital Converters (ADC) · SOT-23-6

XC7468 from Si Change, 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 | VDD | power_in | Power supply input; the device VDD range is 1.5 V to 4.5 V. |
| 2 | GND | power_in | Analog input signal ground; all analog and digital signals are referenced to this pin. |
| 3 | VIN | power_in | Unipolar analog signal input with an input range of 0 V to VDD. |
| 4 | SCLK | input | Serial clock input that clocks out the conversion data and serves as the source of the conversion clock. |
| 5 | SDATA | output | Serial data output carrying the conversion result, MSB first. |
| 6 | CS | input | Active-low chip select that gates SCLK, starts a conversion and frames the output data. |

## CAD (KiCad official)

- Symbol: `XC7468`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `xc7468-etched.step` / `xc7468-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `xc7468.step` / `xc7468.glb` are the bare package body.
