XC2365

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

XC2365 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 a single supply of 4 V to 5.25 V and requires a 1 µF and a 10 nF decoupling capacitor between VDD and GND placed as close to the pins as possible.
2	GND	power_in	Analog input signal ground, to which all analog and digital signals are referenced.
3	AIN	input	Unipolar single-ended analog signal input with an input range of 0 V to VDD.
4	SCK	input	Serial clock input that synchronizes serial data transfer.
5	SDO	tri_state	Serial data output for the conversion result, transmitted MSB first; per the timing section, the pin goes to high impedance after the three leading zeros and 12-bit result are output.
6	CS	input	Active-low chip select that strobes SCK, starts a conversion, and frames the output data.
