Compact Programmable 4-20mA and +/-10V Analog Output Reference Design for AC/Servo Drives

Description

This reference design realizes a small form factor: two channel configurable analog voltage and current output module for AC inverter and servo drives. The integrated industrial output driver: XTR305 offers a compact size when compared to using multiple opamps along with passive components. The output can be programmed to either ±10V or 4mA to 20mA through the host MCU: such as a C2000™ MCU: or manually configured using jumpers. Error flags and output load monitoring capability enable a robust design. The same channel can also be configured as an analog input of ±10V or 4mA to 20mA. The interface fits the C2000 LaunchPad™ Development Kit.
