DACx760EMC-EVM

This user's guide describes the characteristics, operation, and use of the DAC7760 and DAC8760
(DACx760) evaluation boards (EMC-EVMs). This user's guide also discusses how to set up and configure
the software and hardware, and reviews various aspects of the program operation. Throughout this
document, the terms

DAC8760EMC-EVM, evaluation board, evaluation module

, and

EVM

are

synonymous with the DACx760EMC-EVM. This user's guide also includes information regarding operating
procedures and input/output connections, an electrical schematic, printed circuit board (PCB) layout
drawings, and a parts list for the EVM.
