DAC161S997EVM
1 Introduction
The Texas Instruments DAC161S997EVM evaluation module (EVM) helps designers evaluate the
operation and performance of the DAC161S997 4-20mA Loop Drive with SPI control. The EVM contains a
low cost MSP430G2553 microcontroller which comes pre-loaded with firmware to communicate with the
Labview based PC Software. A JTAG header is provided which can be used to program custom firmware.
A general purpose header with SPI and microcontroller GPIOs is provided to ease development of sensor
transmitters and other applications.
The EVM contains one DAC161S997 and is configured as Loop-Powered 2-Wire Transmitter see Table 1 .
