EVM Operation
This chapter covers in detail the operation of the EVM to provide guidance to
the user in evaluating the onboard DAC and interfacing the EVM to a host
processor.
See the specific DAC data sheet, as listed in the Related Documentation from
Texas Instruments section of this user’s guide, for more information about the
DAC serial interface and other related topics.
The EVM board is factory tested and configured to operate in the bipolar output
mode.
