Common-Mode Voltage Input/Output. Bypass to GND with a ≥ 0.1µF capacitor.
Analog Supply Voltage. Bypass each supply pin to GND with a 0.1µF capacitor. The analog
supply voltage accepts a 2.7V to 3.6V input range.
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.
Low: Straight offset binary.
Sleep Mode Input.
High: Deactivates the two ADCs, but leaves the reference bias circuit active.
Low: Normal operation.
Power-Down Input.
High: Power-down mode.
Low: Normal operation.
Output Enable Input.
High: Digital outputs disabled.
Low: Digital outputs enabled.
