Si Change · Analog To Digital Converters (ADC) · SOT-23-6
XCS7477 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; supply is 4 V to 5.25 V, and VDD must be set greater than or equal to the maximum VIN to avoid saturating the maximum conversion code. |
| 2 | GND | power_in | Analog input signal ground and the common ground reference for all circuits; all analog and digital signals are referenced to this pin. |
| 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 clocks the conversion process; the conversion ends at the 14th falling edge of SCLK. |
| 5 | SDATA | tri_state | Serial data output that delivers the conversion result MSB first after four leading zeros, and enters tri-state after the 14th SCLK falling edge. |
| 6 | CS | input | Active-low chip select that both starts a conversion and frames the serial data output; if pulled high before 10 SCLK cycles, the conversion is aborted and no valid data is produced. |
