Description
Most Significant Data Bit (MSB).
Data Bit 10 to Data Bit 1.
Least Significant Data Bit (LSB).
In pin mode, active high powers down chip.
In SPI mode, this pin is the serial port chip select (active low).
Full-Scale Current Output Adjust.
Reference Input/Output. Serves as reference input when internal reference disabled. Serves as 1.0 V reference
output when internal reference is activated. Requires a 0.1 μF capacitor to ACOM when internal reference is
activated.
Analog Common.
DAC Current Output. Full-scale current is sourced when all data bits are 1s.
Complementary DAC Current Output. Full-scale current is sourced when all data bits are 0s.
Adjustable Output Common Mode. Refer to the Theory of Operation section for details.
Analog Supply Voltage (1.7 V to 3.6 V).
Selects SPI mode or pin mode operation. Active high for pin mode operation. Active low for SPI mode
operation. Pulse high to reset SPI registers to default values.
In pin mode, this selects the input data format. Connect to DCOM for straight binary, DVDD for twos
complement.
In SPI mode, this pin acts as SPI data input/output.
In pin mode, this pin selects the clock input type. Connect to CLKCOM for single-ended clock receiver
(drive CLK+ and float CLK–). Connect to CLKVDD for differential receiver.
In SPI mode, this pin is the serial data clock input.
Clock Common.
Negative Differential Clock Input.
Positive Differential Clock Input.
Clock Supply Voltage (1.7 V to 3.6 V).
Digital Common.
No Connect.
Digital Supply Voltage (1.7 V to 3.6 V).
