XC11665A

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

XC11665A 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 VDD supply should be set greater than or equal to the maximum input signal to avoid saturation of codes, and the XC11665A operates from 3.0 V to 4.5 V.
2 GND power_in The ground return for the supply and signals.
3 AIN input Analog input that can range from 0 V to VDD.
4 SCLK input Digital clock input that directly controls the conversion and readout processes.
5 DOUT output Digital data output, with samples clocked out of this pin on the falling edges of SCLK.
6 CS input Chip select; a conversion process begins on the falling edge of CS.
