ADC122S051QIMM

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

ADC122S051QIMM from Texas Instruments, in a VSSOP-8. 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 CS input Chip select: a falling edge on CS starts a conversion, and conversions continue as long as CS is held low.
2 VA power_in Positive supply, to be connected to a quiet +2.7V to +5.25V source and bypassed to GND with a 1 µF capacitor and a 0.1 µF monolithic capacitor located within 1 cm of the power pin.
3 GND power_in Ground return for the die.
4 IN2 input Analog input channel 2, which can range from 0V to VA.
5 IN1 input Analog input channel 1, which can range from 0V to VA.
6 DIN input Digital data input through which the Control Register is loaded on rising edges of SCLK; digital input voltage range is −0.3V to VA.
7 DOUT output Digital data output, with samples clocked out on falling edges of the SCLK pin.
8 SCLK input Digital clock input that directly controls the conversion and readout processes; clock frequency range is 50 kHz to 16 MHz.
