Feedback Input
Voltage Output. High impedance in shutdown. Output voltage is limited to V
Reset Mode Select (digital input). Connect to V
to select 0 reset output value.
Power-Down Lockout (digital input). Connect to V
down.
Clear DAC (digital input). Clears the DAC to its predetermined output state as set by RS.
Chip-Select Input (digital input). DIN is ignored when CS is high.
Serial-Data Input (digital input). Data is clocked in on the rising edge of SCLK.

Digital Ground
Serial-Data Output
User-Programmable Output. State is set by the serial input.
Shutdown (digital input). Pulling SHDN high when PDL = V
shutdown current of 10µA.
Analog Ground
Reference Input. Maximum V
No Connect
Positive Supply. Bypass to AGND with a 4.7µF capacitor in parallel with a 0.1µF capacitor.
