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.
No Connection
A/B Data Indicator. This digital output indicates CHA data (A/B = 1) or CHB data (A/B = 0) to
be present on the output. A/B follows the external clock signal with typically 6ns delay.
Output Driver Ground
Output Driver Supply Voltage. Bypass to OGND with a capacitor combination of 2.2µF in
parallel with 0.1µF.
Three-State Digital Output, Bit 0 (LSB). Depending on status of A/B, output data reflects
channel A or channel B data.
Three-State Digital Output, Bit 1. Depending on status of A/B, output data reflects channel A or
channel B data.
Three-State Digital Output, Bit 2. Depending on status of A/B, output data reflects channel A or
channel B data.
Three-State Digital Output, Bit 3. Depending on status of A/B, output data reflects channel A or
channel B data.
Three-State Digital Output, Bit 4. Depending on status of A/B, output data reflects channel A or
channel B data.
Three-State Digital Output, Bit 5. Depending on status of A/B, output data reflects channel A or
channel B data.
