ADC121S101CIMFX

Texas Instruments · Analog To Digital Converters (ADC) · SOT-23-6

ADC121S101CIMFX from Texas Instruments, 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 VA power_in Positive supply pin that must be connected to a quiet 2.7-V to 5.25-V 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.
2 GND power_in The ground return for the supply and signals.
3 VIN power_in Analog input that can range from 0 V to VA.
4 SCLK input Digital clock input that directly controls the conversion and readout processes.
5 SDATA output Digital data output whose samples are clocked out of this pin on falling edges of the SCLK pin.
6 CS input Chip select input where a conversion process begins on the falling edge of CS.
