CLASS-T DIGITAL AUDIO AMPLIFIER REFERENCE BOARD
USING DIGITAL POWER PROCESSING (DPP
T M
) TECHNOLOGY
Technical Information
Revision 3.0- March 2002
GENERAL DESCRIPTION
The RB-TA3020 reference board is based on the TA3020 digital audio power
amplifier driver from Tripath Technology. This board is designed to provide a
simple and straightforward environment for the evaluation of the Tripath stereo
TA3020 amplifier. This board can also be used in a bridged configuration for high
power mono output
.
Note: There are two versions of the RB-TA3020, depending on nominal supply
voltage.
RB-TA3020-1 – Nominal supply voltage +/-21V to +/-39V
RB-TA3020-2 – Nominal supply voltage +/-35V to +/-60V
