2. PRODUCT OVERVIEW
2.1 Overview
The DAC128V is a singlewide IP Module board, conforming both mechanically and
electrically to the ANSI VITA/4-1995,
American National Standard for IP Modules . For a
typical IP Module carrier that holds four IP Modules, it can provide up to 32 channels of
DACs for a single slot on a computer bus backplane, or be mixed with other IP Modules
for a more customized, modular I/O system solution.
The DAC128V maintains the highest possible accuracy by minimizing accumulative
errors through the use of the best parts for the tasks to be accomplished.
