Description
Analog Supply Voltage.
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. The 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 serial input register on the rising edge of SCLK. The duty cycle must be
between 40% and 60%.
Serial Data Input. This device accepts 16-bit words. Data is clocked into the serial 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
serial register data.
Digital Ground. Ground reference for digital circuitry.
Logic Power Supply.
