Description

This TI design demonstrates using the MSP430F67791A MCU to accurately measure voltages and currents. This design also demonstrates two dc analog output channels, which can be selected to provide voltage output (±10 V) or current output (±24 mA). The design has a provision for six digital output drivers that are used to drive relays. The functionality of the design can be extended for power measurement. One advantage of this design is that it is a complete subsystem for measuring voltages and currents that also provides a dc analog output proportional to the ac voltage or current used in ac transducer applications. Another advantage of this design is the bidirectional dc analog output.
