Description
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.
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.
Asynchronous Clear Input. The CLR input is falling edge sensitive. When CLR is low, all
LDAC pulses are ignored. When CLR is activated, the serial input register and the DAC
register are cleared to zero scale.
Analog Output Voltage from the DAC.
Digital Ground. Ground reference for digital circuitry.
Analog Supply Voltage.
Ground Reference Point for Both Analog and Digital Circuitry.
Ground Reference Point for Analog Circuitry.
Logic Power Supply.
LDAC Input. When this input is taken low, the DAC register is simultaneously updated
with the contents of the serial input register.
Exposed Pad. For increased reliability of the solder joints and maximum thermal
capability, it is recommended that the pad be soldered to the substrate, GND.
