XC2361

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

XC2361 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, operating from 3.3 V to 5.25 V, and should be kept at or above the maximum input signal to avoid code saturation.
2	GND	power_in	The ground return for the supply and signals, to be decoupled to VDD with 1 µF and 10 nF capacitors placed close to the pins.
3	AIN	input	Analog input that can range from 0 V to VDD.
4	SCK	input	Digital clock input that directly controls the conversion and readout processes.
5	SDO	tri_state	Digital data output that is clocked out on SCK falling edges, with the 12-bit result following three leading zeros and the pin entering three-state after the conversion cycle ends.
6	CONV	input	Chip select input where a falling edge begins a conversion process.
