Pin Description
Analog Outputs (Output) - The full-scale output level is specified in the Analog Characteristics specifi-
cation table.
Reference In (Input) - Analog reference pin.
Reference Out (Output) - Analog reference pin.
Positive Analog Power (Input) - Positive power for the internal analog section.
Negative Analog Power (Input) - Negative power for the internal analog section.
Reset (Input) - The device enters a low-power mode when this pin is driven low.
Mute (Input) - This pin defaults to an active low mute input, and may be configured as an active high
mute input.
Serial Control Port Clock (Input) - Serial clock for the serial control port.
Serial Control Data (Input/Output) - SDA is a data I/O line for the control port interface in I²C Mode.
MOSI is the input data line for the control port interface in SPI Mode.
Default Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 sets the LSB of the default
chip address in I²C Mode. CS is the chip-select signal for SPI format.
Enable Output (Output) - Enable output signal for multi-device serial control chain configuration.
Digital Ground (Input) - Ground reference for the internal digital section.
Digital Power (Input) - Positive power for the internal digital section.
