NAME FUNCTION
1 1 REF Voltage Reference Input
22CS Chip-Select Input
3 3 SCLK Serial Clock Input. Duty cycle must be between 40% and 60%.
4 4 DIN Serial Data Input
55CLR
Clear Input. Logic low asynchronously clears the DAC to code 0 (MAX5441/MAX5443)
or code 32768 (MAX5442/MAX5444).
6 6 OUT DAC Output Voltage
— 7 INV
Junction of Internal Scaling Resistors. Connect to external op amp’s inverting input in
bipolar mode.
— 8 RFB Feedback Resistor. Connect to external op amp’s output in bipolar mode.
79V
DD
Supply Voltage. Use +3V for MAX5443/MAX5444 and +5V for MAX5441/MAX5442.
