Si Change · Analog To Digital Converters (ADC) · SOT-23-6
XC7886 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 single supply is 4 V to 5.25 V, and VDD should be kept greater than or equal to the maximum VIN 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, unipolar with a 0 V to VDD range. |
| 4 | SCLK | input | Serial clock input; it drives the conversion, with the sampling period ending at the third falling edge and the conversion completing at the 16th falling edge. |
| 5 | SDO | output | Serial data output that delivers the 12-bit conversion result MSB first after four leading zeros, and enters tri-state after the 16th falling SCLK edge. |
| 6 | CS | input | Active-low chip select; a falling edge wakes the device and starts a conversion, and taking CS high before 10 SCLK cycles aborts the conversion with no valid data on the next cycle. |
