Positive Analog Input. Positive side of fully differential analog input. Bypass AIN+ to GND with a
0.1µF or greater capacitor.
Negative Analog Input. Negative side of fully differential analog input. Bypass AIN- to GND with a
0.1µF or greater capacitor.
Ground. Connect to star ground.
Analog Positive Supply Voltage. Connect AV
to GND with a 0.1µF capacitor.
Digital Positive Supply Voltage. Connect DV
to GND with a 0.1µF capacitor.
Segment Current Set. Connect to ground through a resistor to set the segment current. See Table
7 for segment-current selection.
V/I Converter Regulated Supply Output (5.2V typ)
REG_VDD Control. Drives the gate of external depletion-mode FET.
Regulator/Reference Buffer Supply. Connect to a 4.75V to 5.25V power supply.
Regulator Compensation Node. Connect a 0.1µF capacitor from CMP to REG_FORCE.
DAC Analog Supply. Connect DAC_VDD to a +2.7V to +5.25V power supply.
DAC Voltage Output. DAC output impedance is typically 6.2kΩ.
V/I Converter Input
4–20mA (0 to 16mA) Current-Loop Output. Referenced to GND.
DAC Analog Ground. Connect to star ground.
V/I Converter Analog Ground. Connect to star ground.
V-to-I Converter/DAC Reference Input. Connect a voltage source for external reference operation
or leave floating for internal reference. Bypass REF_DAC with a 0.1µF capacitor to GND for either
internal or external reference operation.
