No Connection. Not internally connected.
DAC Current-Source Output. OUTI sources either from 0 to 20mA or from 4–20mA.
DAC Current-Output Positive Supply. Connect V
+40V to power the DAC current-output (OUTI) buffer. Bypass V
AGND, as close as possible to the device.
OUTI Noise-Limiting Capacitor Connection. Connect a 22nF capacitor from COMPI to V
reduce transient noise at OUTI.
Current-Output Range Selection Input. Connect OUTI4/0 to AGND to select the 0 to 20mA OUTI
current-output range. Connect OUTI4/0 to V DDI to select the 4–20mA OUTI current-output range.
The OUTI current range can also be set by software. When using software to set the OUTI current
range, connect OUTI4/0 to AGND.
Buffered Voltage Reference Input. Connect an external +4.096V voltage reference to REF. Bypass
REF with a 0.1µF capacitor to DACGND, as close as possible to the device. Use a 1kΩ resistor in
series to the reference input for optimum performance.
DAC Analog Ground. Connect DACGND, DACGNDS, DUTGND, and DUTGNDS together on a
low-noise ground plane with a star connection.
DAC Analog Sense Ground. Connect DACGND, DACGNDS, DUTGND, and DUTGNDS together
on a low-noise ground plane with a star connection.
Voltage/Current Configuration Input. CNF1 and CNF0 control the OUTV and OUTI outputs. See
Tables 13 and 14.
