ADX122AMSOP10

analogysemi · Analog To Digital Converters (ADC) · MSOP-10

ADX122AMSOP10 from analogysemi, in a MSOP-10. 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 SCLK input Serial clock input with Schmitt-trigger hysteresis; keep it clean, and the serial interface resets if SCLK is held low for 28 ms.
2 CS input Chip select, active low; hold low during serial communication and connect to GND if not used.
3 GND power_in Ground reference for the device.
4 AIN0 input Analog input 0; leave unconnected or tie to VDD if not used.
5 AIN1 input Analog input 1; leave unconnected or tie to VDD if not used.
6 AIN2 input Analog input 2; leave unconnected or tie to VDD if not used.
7 AIN3 input Analog input 3; leave unconnected or tie to VDD if not used.
8 VDD power_in Power supply; connect a 100 nF decoupling capacitor between VDD and GND.
9 DOUT/DRDY output Serial data output combined with data-ready; goes low to indicate new conversion data is available, and is active low.
10 DIN input Serial data input, latched on the SCLK falling edge; the device never drives this pin.
