FUNCTION

Voltage Reference Input

Chip-Select Input

Serial Clock Input. Duty cycle must be between 40% and 60%.

Serial Data Input

Clear Input. Logic low asynchronously clears the DAC to code 0 (MAX5441/MAX5443)

or code 32768 (MAX5442/MAX5444).

DAC Output Voltage

Junction of Internal Scaling Resistors. Connect to external op amp’s inverting input in

bipolar mode.

Feedback Resistor. Connect to external op amp’s output in bipolar mode.

Supply Voltage. Use +3V for MAX5443/MAX5444 and +5V for MAX5441/MAX5442.
