DESCRIPTION  
–
–
Soft Muting With Gain Ramp Control  
Common-Mode Ramping  
The TAS5414C-Q1 and TAS5424C-Q1 are four-  
channel digital audio amplifiers designed for use in  
automotive head units and external amplifier  
modules. They 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 TAS5414C-Q1 uses  
single-ended analog inputs, whereas the TAS5424C-  
Q1 employs differential inputs for increased immunity  
to common-mode system noise. The digital PWM  
topology of the device 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. The device incorporates all the  
functionality needed to perform in the demanding  
OEM applications area. The devices have built-in  
load diagnostic functions for detecting and diagnosing  
misconnected outputs to help to reduce test time  
during the manufacturing process.
