www.ti.com Overview
This EVM is configured with two RCA phono input connectors for analog input; the output signal is
available on two RCA phono connectors. The power supply is connected via a two-pin, 2,54-mm header.
This evaluation board is designed for testing applications such as set-top boxes, LCD/PDP TVs, Blu-ray
Disc™ DVD players, DVD mini-component systems, home theater-in-a-box (HTIB) systems, or
soundcards.
This document presents EVM specifications, audio performance measurements graphs, and design
documentation that includes complete circuit descriptions, schematic diagrams, a parts list, and PCB
layout design. Gerber (layout) files are available from the TI Web site at www.ti.com.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with
the DRV632EVM.
