ADC122S021CIMM

Texas Instruments · Analog To Digital Converters (ADC) · VSSOP-8

ADC122S021CIMM from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CS input Chip select; a conversion process begins on the falling edge of CS and conversions continue as long as CS is held low.
2 VA power_in Positive supply pin, to be connected to a quiet +2.7V to +5.25V source and bypassed to GND with a 1 µF and a 0.1 µF capacitor located within 1 cm of the pin.
3 GND power_in Ground return for the die.
4 IN2 passive Analog input channel 2; signal can range from 0V to VA.
5 IN1 passive Analog input channel 1; signal can range from 0V to VA.
6 DIN input Digital data input; the Control Register is loaded through this pin on rising edges of SCLK.
7 DOUT tri_state Digital data output; conversion result samples are clocked out of this pin on falling edges of SCLK, and the pin is high-impedance when CS is high.
8 SCLK input Digital clock input that directly controls the conversion and readout processes.
