I got the EVM for the TPA6132A and tested it on the bench last night. All I can say is "WOW". I am beyond impressed with this device. Running from a 7805 and a 9V battery, the rails were very clean. I tested it with an Audiophile sound card and a variety of different types of music. Just incredible. I've been using devices like the LM4880 in the past, and wanted to try one of the "capless" devices. I won't look back. I haven't run any low voltage tests yet, though in this particular design it's of less importance than if I were doing something that ran directly off the battery. Design in complete.
