EVM Overview
This user
’
s guide describes the characteristics, operation, and use of the THS56X1 evaluation module
(EVM). The THS56X1 EVM can be connected to the TMS320C542/TMS320C54xx DSP and controlled by
very user friendly software

s Code Composer Development Environment, or to a pattern generator.
This gives the user possibilities to measure the performance of the CommsDAC, to evaluate different
types of DAC output interface circuits, and to evaluate an external voltage reference (Vref) suitable for use
with the THS56X1A family of digital-to-analog converter (CommsDAC). The CommsDAC family consists of
the pin compatible 8-bit resolution THS5641A, 10-bit resolution THS5651A, 12-bit resolution THS5661A
and 14-bit resolution THS5671A digital-to-analog converter (DAC).
