Description
For bipolar ±10 V output range, this pin should be tied to 0 V.
This is the voltage reference input for the DAC. Connect to external 5 V reference for specified bipolar ±10 V output.
Load DAC Logic Input (Active Low). When taken low, the contents of the shift register are transferred to the DAC
register. LDAC can be tied permanently low, enabling the outputs to be updated on the rising edge of SYNC.
Serial Data Input. This device accepts 16-bit words. Data is clocked into the input register on the falling edge of SCLK.
Active Low Control Input. Data is clocked into the shift register on the falling edges of SCLK.
Active Low Readback Enable Function. This function allows the contents of the DAC register to be read. Data
from the DAC register is shifted out on the SDO pin on each rising edge of SCLK.
Clock Input. Data is clocked into the input register on the falling edge of SCLK.
Serial Data Out. This pin is used to clock out the serial data previously written to the input shift register or can be
used in conjunction with RBEN to read back the data from the DAC register. This is an open drain output; it
should be pulled high with an external pull-up resistor. In standalone mode, SDO should be tied to GND or left
high impedance.
This allows the DAC to be put into a power-down state.
Ground Reference.
