• On: Enables data output randomizer
Two's Complement: Enables two's complement mode
• Off (Default): Selects offset binary mode
• On: Selects two's complement mode
Sleep Mode: Selects between normal operation, sleep
mode:
• Off (Default): Entire ADC is powered, and active
• On: The entire ADC is powered down.
Channel 1 Nap: Selects between normal operation and
putting channel 1 in nap mode.
• Off (Default): Channel one is active
