Offset Adjustment. Connect to AGND for no offset.
Voltage Output. High impedance when in shutdown. The output voltage is limited to V
Reset Mode Select (digital input). Connect to V
DGND to select 0 reset output voltage.
Power-Down Lockout. (digital input). Connect to V
software and hardware shutdown.
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.
Serial-Data Input (digital input). Data is clocked in on the rising edge of SCLK.
Serial Clock Input (digital input).
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 Connection
Positive Supply. Bypass to AGND with a 4.7µF capacitor in parallel with a 0.1µF capacitor.
