DescriptionThe TCA2002 is a two channel audio controller that uses Tripath's proprietary Digital Power Processing (DPPTM) technology. When combined with switching power output stages, the TCA2002 allows the implementation of a complete Class-T audio amplifier. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
The TCA2002 is pin compatible with the Tripath's previous stereo controllers, the TC2000 and TC2001. The basis for Tripath controllers is a proprietary, fully scalable, feedback structure. The TCA2002 is capable of single ended or bridged operation, with single or split power supplies. When mated with the appropriate power stage, amplifiers with output powers of 25W to 1000W, or more, are possible.
Both Tripath power stages as well as third party power stages, whether integrated, or discrete, can be used to make a complete, high-performance switching amplifier. Many features on the TCA2002 have been improved including increased supply range, elimination of turn-on pop, and automatic recovery from an overcurrent fault.
