Si Change · Analog To Digital Converters (ADC) · SOT-23-6
XC7910 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 with a range of 3.3 V to 5.25 V; VDD should be kept at or above the maximum VIN input signal to avoid saturating the maximum conversion code. |
| 2 | GND | power_in | Analog input signal ground, to which all analog and digital signals are referenced. |
| 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 is the source of the conversion clock. |
| 5 | SDATA | output | Serial data output of the conversion result, MSB first, which enters tri-state after the 16th SCLK falling edge. |
| 6 | CS | input | Active-low chip select that gates SCLK, starts a conversion on its falling edge, and frames the output data; it should not be raised before the 10th SCLK edge or the conversion is aborted. |
