XC7466

Si Change · Analog To Digital Converters (ADC) · SOT-23-6

XC7466 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; the datasheet specifies operation from a single 1.5 V to 4.5 V supply, and a 1 µF and 10 nF decoupling capacitor are required between VDD and GND placed as close to the pins as possible.
2 GND power_in Ground for signal and power supply; all analog and digital signals are referred to this pin.
3 VIN power_in Analog input with a stated input range of 0 V to VDD (unipolar, single-ended).
4 SCLK input Serial clock input used for clocking data out and as the source of the conversion clock; the third falling edge after CS falls starts the hold mode and digitization.
5 SDATA tri_state Serial data output of the conversion result, MSB first; the pin is 3-stated when the conversion cycle ends after 16 SCLK falling edges.
6 CS input Active-low chip select that initiates conversions and frames the serial data transfer.
