No Connection. Not internally connected.
DAC B Output-Mode Selection Input. Selects unipolar or bipolar output. Logic high = unipolar, logic
low = bipolar. In unipolar mode, the analog output range is 0 to 2 x V
output range is (-2 x V
Active-Low Shutdown Input. Pulling SHDN low forces the DAC buffers into high impedance. Drive
SHDN high for normal operation.
Active-Low Load DAC Input. DAC A and DAC B are updated with information in the input register on
the LDAC falling edge.

Digital Ground
Digital Power Input. Connect V
and 0.1µF capacitor in parallel as close to the device as possible.
Serial-Data Output. Data is clocked out on SCLK’s falling edge. DOUT is high impedance when CS is
high. Data shifted into DIN appears at DOUT 16.5 clock cycles later.
Serial-Clock Input. SCLK clocks data in and out of the serial interface.
Serial-Data Input. Data is clocked in on the rising edge of SCLK.
Active-Low Chip-Select Input. Data is not clocked into DIN unless CS is low.
DAC A Output-Mode Selection. Selects unipolar or bipolar output. Logic high = unipolar, logic low =
bipolar. In unipolar mode, the analog output range is 0 to 2 x V
range is (-2 x V
DAC A Output
DAC A Sense Ground. Connect to AGND.
Reference Input for DAC A
Positive Analog-Power Input. Connect V
AGND with a 10µF and 0.1µF capacitor in parallel as close to the device as possible.
DAC B Reference Input
Analog Ground
DAC B Sense Ground. Connect to AGND.
DAC B Output
Negative Analog-Power Input. For single-supply operation, connect V
operation, connect V
0.1µF capacitor in parallel, as close to the device as possible.
