The DAC8234EVM features the DAC8234 digital to analog converter. The EVM module provides a quick and easy way to evaluate the functionality and performance of this high resolution serial input Digital to Analog Converter (DAC). The DAC8234EVM is designed to work by default for bipolar output range, but it can also be configured for unipolar output range by a simple switch change. The EVM provides the serial interface header to easily attach to any host microprocessor or TI DSP base system. Installed precision reference voltages of +5 VDC and +2.5VDC are selectable using onboard switches S2 and S3. REF5050 (+5.0 VDC source) and REF5025 (+2.5VDC) are pin compatible with the REF50xx family allowing a wide variety of reference values.
