I²C Format SDA (Input/Output) - Acts as an input/output data pin. An external pull-up resistor is
required for I²C control port operation.
SPI Format CDOUT (Output) - Acts as an output only data pin.
I²C Format, SCL (Input) - Serial clock for the serial control port. An external pull-up resistor is
required for I²C control port operation.
SPI Format, CCLK (Input) - Serial clock for the serial control port.
I²C Format, AD0 (Input) - Forms the device address input AD[0].
SPI Format, CS (Input) - Acts as the active low chip select input.
I²C Format, AD1 (Input) - Forms the device address input AD[1].
SPI Format, CDIN (Input) - Becomes the input data pin.
Interrupt (Output) - Indicates an interrupt condition has occurred.
FILT+ (Output) - Full-scale reference voltage for ADC.
ADC Common-Mode Voltage (Output) - Filter connections for the ADC internal quiescent refer-
ence voltage.
Analog Ground (Input) - Analog ground reference.
Analog Power (Input) - Positive power for the internal analog section.
Bias Voltage (Output) - Positive reference voltage for the internal DAC.
