Si Change · Analog To Digital Converters (ADC) · SOT-23-6
XCS7476 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, which also serves as the ADC reference voltage; the supply is 4 V to 5.25 V and should be set greater than or equal to the maximum VIN signal to avoid saturation at the maximum conversion code. |
| 2 | GND | power_in | Analog input signal ground and the common ground reference for all circuits, against which all analog and digital signals are referenced. |
| 3 | VIN | power_in | Single-ended analog signal input with an input range of 0 V to VDD. |
| 4 | SCLK | input | Serial clock input that provides the serial clock and acts as the clock source for the conversion process. |
| 5 | SDATA | output | Serial data output that delivers the conversion result MSB first, preceded by four leading zeros, and goes to tri-state at the end of the conversion on the 16th falling SCLK edge. |
| 6 | CS | input | Active-low chip select that both starts a conversion and frames the serial data output. |
