About the Kit
The THDB_ADA (ADA) daughter board is designed to provide DSP solution on DE series and
Cyclone III Starter Kit, or other boards with HSMC or GPIO interface. It is equipped with one ADC
(Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter) each, to provide
dual-channel ports. This chapter provides users key information about the kit.
