DESCRIPTION  
Patented Pop- and Click-Reduction  
Technology  
The TAS5414A and TAS5424A are four-channel  
digital audio amplifiers designed for use in automotive  
head units and external amplifier modules. The  
TAS5414A and TAS5424A provide four channels at  
23 W continuously into 4 Ω at less than 1% THD+N  
from a 14.4-V supply. Each channel can also deliver  
38 W into 2 Ω at 1% THD+N. The TAS5414A uses  
single-ended analog inputs, while the TAS5424A  
employs differential inputs for increased immunity to  
common-mode system noise. The digital PWM  
topology of the TAS5414A and TAS5424A provides  
dramatic improvements in efficiency over traditional  
linear amplifier solutions. This reduces the power  
dissipated by the amplifier by a factor of ten under  
typical music playback conditions. High efficiency is  
accomplished without the need for complicated  
power-supply schemes. Multiple TAS5414As or  
TAS5424As can be synchronized to meet  
high-channel-count applications.
