GENERAL DESCRIPTION
The EB-TA1101B evaluation board is based on the TA1101B, digital audio power
amplifier from Tripath Technology. The board is designed to provide a simple and
straightforward environment for the evaluation of the Tripath TA1101B. The board can
be connected to a +12V supply using cables with banana connectors. Audio inputs are
standard RCA jacks. The TA1101B provides amplification for two channels of audio.
Signal outputs are on four banana connectors to which any 4Ω or 8Ω passive speaker
may be connected.
