Common-Mode Voltage Input/Output. Bypass to GND with a ≥ 0.1µF capacitor.
Analog Supply Voltage. Bypass each pin to GND with a 0.1µF capacitor. The analog supply
accepts an input range of 2.7V to 3.6V.
Analog Ground
Channel A Positive Analog Input. For single-ended operation, connect signal source to INA+.
Channel A Negative Analog Input. For single-ended operation, connect INA- to COM.
Channel B Negative Analog Input. For single-ended operation, connect INB- to COM.
Channel B Positive Analog Input. For single-ended operation, connect signal source to INB+.
Converter Clock Input
T/B selects the ADC digital output format.
High: Two’s complement.
