Description
Analog Output Voltage from the DAC.
Ground Reference Point for Analog Circuitry.
Voltage Reference Input for the DAC. Connect to an external 2.5 V reference. Reference can range from 2 V to V
Logic Input Signal. The chip select signal is used to frame the serial data input.
Clock Input. Data is clocked into the input register on the rising edge of SCLK. Duty cycle must be between 40% and 60%.
Serial Data Input. This device accepts 16-bit words. Data is clocked into the input register on the rising edge of SCLK.
Digital Ground. Ground reference for digital circuitry.
Analog Supply Voltage, 5 V ± 10%.
Description
Feedback Resistor Pin. In bipolar mode, connect this pin to the external op amp output.

Ground Reference Point for Analog Circuitry (Force).
Ground Reference Point for Analog Circuitry (Sense).
Voltage Reference Input (Sense) for the DAC. Connect to an external 2.5 V reference. Reference can range from 2 V to V
Voltage Reference Input (Force) for the DAC. Connect to an external 2.5 V reference. Reference can range from 2 V to V
Logic Input Signal. The chip select signal is used to frame the serial data input.
Clock Input. Data is clocked into the input register on the rising edge of SCLK. Duty cycle must be between 40% and 60%.
No Connect.
Serial Data Input. This device accepts 16-bit words. Data is clocked into the input register on the rising edge of SCLK.
LDAC Input. When this input is taken low, the DAC register is simultaneously updated with the contents of the
input register.
Digital Ground. Ground reference for digital circuitry.
Connected to the Internal Scaling Resistors of the DAC. Connect the INV pin to external op amps inverting input in
bipolar mode.
Analog Supply Voltage, 5 V ± 10%.
