The following parts: J1, J3, R7, R9, and R10 are not installed.
(2)
P2, P4, and P6 parts are not shown in the schematic diagram. All the P-designated parts are installed in the bottom side of the
pc board opposite the J-designated counterpart. For example, J2 is installed on the top side while P2 is installed in the bottom
side opposite of J2.
This section covers in detail the operation of the EVM to provide guidance to the user in evaluating the
onboard DAC and how to interface 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’s serial interface and other related topics.
The EVM board is factory tested and configured to operate in the bipolar output mode.
