Pin Description
Voltage Output. High impedance when in shutdown. The output voltage is limited to VDD.
OUT
2
Power-Down Lockout. (digital input). Connect to VDD to allow shutdown. Connect to DGND to disable
software and hardware shutdown.
PDL
4
Reset Mode Select (digital input). Connect to VDD to select midscale reset output voltage. Connect to
DGND to select 0 reset output voltage.
RS
3
Chip-Select Input (digital input). DIN ignored when CS is high.
CS
6
Serial Clock Input (digital input).
SCLK
8
Serial-Data Input (digital input). Data is clocked in on the rising edge of SCLK.
DIN
7
Clear DAC. (digital input) Clears the DAC to either zero or midscale as determined by RS.
CLR

Serial-Data Output
DOUT
10
Shutdown (digital input). Pulling SHDN high when PDL = VDD places the chip in shutdown with a maximum
shutdown current of 10A.
SHDN
12
User-Programmable Output. State is set by the serial input.
UPO
11
Reference Input. Maximum VREF is VDD - 1.4V.
