Si Change · Analog To Digital Converters (ADC) · SOT-23-6
XC081S051 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 | VA | power_in | Power supply input (3.3 V to 5.25 V), which also serves as the ADC reference; VA must be set greater than or equal to the maximum VIN input signal to avoid saturating the maximum conversion code. |
| 2 | GND | power_in | Analog input signal ground; all analog and digital signals are referenced to this pin. |
| 3 | VIN | power_in | Single-ended analog signal input with a range of 0 V to VA. |
| 4 | SCLK | input | Serial clock input that directly controls the conversion and readout process; a conversion starts on CS falling with SCLK, and the 12th falling SCLK edge ends the cycle. |
| 5 | SDATA | output | Serial data output that delivers the 8-bit result MSB first after three leading zeros and enters tri-state after the 12th falling SCLK edge. |
| 6 | CS | input | Active-low chip select that starts a conversion on its falling edge; it should be raised after 12 SCLK cycles, and raising it before 10 SCLK cycles aborts the conversion with no valid data. |
