EVM Operation

2.2 EVM Performance Results

The EVM performance test is performed using a high density DAC bench test board, an Agilent 3458A

digital multimeter and a PC running the LabVIEW

software. The EVM board is tested for all codes of the

device under test (DUT) and is allowed to settle for 1ms before the meter is read. This process is repeated

for all codes to generate the measurements for INL and DNL results.

The results of the DAC8831/32EVM characterization test are shown in Figure 6. Take note that the

DAC8831/32 uses the OPA735 for the output buffer.

3 EVM Operation

This chapter 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.

Refer to 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.
