BP-DAC11001EVM

3.2.2.3

DAC Quick-Start Page

The

DAC Quick-Start

page provides the functions to quickly get started with the EVM. The basic

initialization settings are meant for basic dc operation; whereas, the advanced settings are meant for ac
functionality, such as settling time and total harmonic distortion (THD). Write a decimal code to the DAC
output input box to get the corresponding analog output.
