Industrial Analog Current/
Voltage-Output Conditioners
Pin Description (continued)
PIN
NAME
FUNCTION
19
OUT
Analog Output. The analog voltage or current output range at OUT is programmable. See Tables
1 to 4 for possible output range settings.
Positive Output Driver Supply Voltage Input. AVDDO provides power to the driver output stage.
20
AVDDO
Bypass AVDDO to AVDD with a 0.1FF capacitor. Use diodes as shown in the Typical Operating
Circuit/Functional Diagram to ensure a voltage difference of 2V to 3.5V between AVDD and
AVDDO.
21
SENSERP
Sense Resistor Positive Connection. See the Typical Operating Circuit/Functional Diagram for the
typical connection.
22
SENSERN
Sense Resistor Negative Connection. See the Typical Operating Circuit/Functional Diagram for the
typical connection.
23
SENSEVN
Kelvin Sense Voltage Negative Input. See the Typical Operating Circuit/Functional Diagram for the
typical connection.
25
SENSEVP
Kelvin Sense Voltage Positive Input. See the Typical Operating Circuit/Functional Diagram for the
typical connection.
26
AVDD Positive Analog Supply Voltage Input. Bypass AVDD to AGND with a 0.1FF capacitor.
28
AVSS
Negative Analog Supply Voltage Input. Bypass AVSS to AGND with a 0.1FF capacitor.
29
MON
Load Monitoring Output. MON provides an analog 0 to 3V output. See the Output Monitor section.
30
CS1
Active-Low SPI Chip-Select Input 1. See the SPI Interface section.
31
CS2
Active-Low SPI Chip-Select Input 2. See the SPI Interface section.
