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.
