3.1 DAC8560EVM

The DAC8560EVM is an evaluation module designed to easily evaluate the functionality and performance of the single-channel serial input DAC with up to 16-bits of resolution. The device has a 2.5 V internal reference that is enabled by default and can be output to a MSP ADC external reference pin. The EVM has a serial interface to allow for communication with a host Microprocessor, including any of the numerous LaunchPad development kits supplied by TI, and can furthermore be solely supplied by the MSP VCC rail. Table 2 lists the proper DAC8560EVM jumper orientations needed to run the example as intended. More information about the DAC can be found in the DAC8560EVM User's Guide (SLAU211).
