TCD6001
6 CHANNEL CLASS-T DIGITAL AUDIO PROCESSOR USING
DIGITAL POWER PROCESSINGTM TECHNOLOGY
PRELIMINARY INFORMATION
Revision 0.9– July 2005
General Description
The TCD6001 is a high-performance 6-channel digital audio amplifier processor. It accepts 6 digital audio
channels (3 pairs), and outputs 4 complementary single-bit digital data streams, suitable for driving Tripath
switching output stages. The other two channels of digital input are converted and routed to a stereo line-out
stage capable of driving headphones.
The TCD6001 accepts data at audio sample rates ranging from 32kHz to 192kHz and incorporates digital
interpolation and sigma-delta conversion to produce streamed digital output signals. When combined with
switching output stages, the TCD6001 allows the implementation of a complete digital audio system
incorporating Class-T Digital Audio Amplification.
