1.1 Overview
Welcome to use this self-made 2*100W audio amplifier board which is a perfect class-D
architecture integrated TC2000 and TP2050 chips to achieve the single-channel 100W
power output. With high efficiency, it especially is available for the outdoor venues where
power supply is always in consideration. Moreover, integrated with TC2000 and TP2050
chips of Tripath, this board also supports four-channel amplification and can be powered
by any DC power supply ranging from +10 to 36V, which can be used to drive any 4Ωor
8Ωpassive speakers.
TC2000 is a dual channel audio controller produced by Tripath using its patent Digital
Power Processing technology (DPPTM), combined with switching power output stages
TP2050, 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 double-channel audio amplification of up to 100W each.
Resistance 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..
