CI7476

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

CI7476 from Tokmas, 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 gives a single 3.3 V to 4.8 V supply for the CI7476E/77E/78E and a single 4 V to 5.25 V supply for the CI7476/77/78.
2 GND power_in Ground return for the supply and signals.
3 VIN power_in Analog input that can range from 0 V to VDD.
4 SCLK input Digital clock input that directly controls the conversion and readout processes.
5 SDATA output Digital data output; the output samples are clocked out of this pin on falling edges of SCLK.
6 CS input Chip select; a conversion process begins on the falling edge of CS.
