Pin Description
FUNCTION
Common-Mode Voltage Input/Output. Bypass to GND with a ≥0.1µF capacitor.
Analog Supply Voltage. Bypass to GND with a capacitor combination of 2.2µF in parallel with 0.1µF.
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.
