XC7888 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; VDD must be set greater than or equal to the maximum VIN input signal to avoid saturation at the maximum conversion code, with a 4 V to 5.25 V single supply. |
| 2 | GND | power_in | Analog input signal ground; all analog and digital signals are referenced to this pin. |
| 3 | VIN | power_in | Analog signal input for the single-ended unipolar channel, with a 0 V to VDD input range. |
| 4 | SCLK | input | Serial clock input that drives the conversion and data transfer, supporting a serial interface up to 16 MHz, with the first falling edge after CS low ending the sampling phase on the third falling edge. |
| 5 | SDO | output | Serial data output that delivers the 8-bit conversion result MSB first after four leading zeros, and enters tri-state on the 12th falling edge of SCLK to end the conversion cycle. |
| 6 | CS | input | Active-low chip select that starts a conversion when pulled low; it is pulled high after 12 SCLK cycles, and must stay high for at least 1 µs after SDO tri-states before the next conversion is started. |
