↑+ indicates a positive logic transition; ↓– indicates a negative logic transition; X = don’t care.
CS and CLK are interchangeable.
Returning CS high avoids an additional false clock of serial data input.
Do not clock in serial data while LD is low.

Description
Positive Supply. Nominal value 5 V ± 5%.
Chip Select. Active low input.
Clock Input. Clock input for the internal serial input shift register.
Serial Data Input. Data on this pin is clocked into the internal serial register on positive clock edges of the
SCLK pin. The most significant bit (MSB) is loaded first.
Serial Register Data Write to DAC Register. Active low input that writes the serial register data into the DAC
register. Asynchronous input.
Clear DAC Register. Active low digital input that clears the DAC register to zero, setting the DAC to minimum
scale. Asynchronous input.
Ground. Analog ground for the DAC. This also serves as the digital logic ground reference voltage.
Voltage Output from the DAC. Fixed output voltage range of 0 V to 4.095 V with 1 mV/LSB. An internal
temperature stabilized reference maintains a fixed full-scale voltage independent of time, temperature, and
power supply variations.
