Overview

Welcome to use this 2*100W Class-D audio amplifier board by Sure Electronics. As an
upgraded version of the original AA-AB013, this board integrates an external extensible
interface to connect the matching product of a volume control board and a rotary encoder
board for volume control. It's suitable for amplifier enthusiasts or hobbyists to finish a
complete amplifier system.
This amplifier board integrates Tripath's high performance TC2000 and TP2050 chips
supporting dual channel audio amplification. Powered by any DC voltage from 10V to 32V,
this high efficiency amplifier board is capable of outputting up to 100W per channel. It can
be used to drive 4Ω or 8Ω passive speakers.
TC2000 is a dual channel audio controller produced by Tripath using its patent Digital
Power Processing technology (DPP
TP2050, it can achieve class-T audio power amplification and 50W continuous average
power per channel, as well as lower THD+N and higher S/N ratio .
For 100W power output, this amplifier board integrates one TC2000 chips and two TP2050
chips so that it supports dual-channel audio amplification of up to 100W each. Resistance
and capacity components of high quality are used to gain the perfect timber, finally realize
high S/N ratio, low THD+N, wide frequency response range etc.
In addition, auto fan control function is utilized so that the cooling fun will self-adjust its
rotating speed when the temperature of chips is too high, ensuring the normal working of
the chips, and will automatically shutdown when the temperature of chips keeps low,
ensuring the fun's own long service life.
