OS
OUT
Offset Adjustment. Connect to AGND for no offset.
Voltage Output. High impedance when in shutdown. The output voltage is limited to V
DD
.
PIN

UPO
User-Programmable Output. State is set by the serial input.

SHDN
Shutdown (digital input). Pulling SHDN high when
PDL

DD
places the chip in shutdown with a maximum
shutdown current of 10μA.

CLR
CS
Clear DAC (digital input). Clears the DAC to either zero or midscale as determined by RS.
Chip Select Input (digital input). DIN ignored when
CS
is high.

SCLK
Serial-Data Input (digital input). Data is clocked in on the rising edge of SCLK.
Serial Clock Input (digital input)

RS
Reset Mode Select (digital input). Connect to V
DD
to select midscale reset output voltage. Connect to
DGND to select 0 reset output voltage.
4
PDL
Power-Down Lockout (digital input). Connect to V
DD
to allow shutdown. Connect to DGND to disable
software and hardware shutdown.
