SLOS955 – DECEMBER 2016 TAS5414C Four-Channel Aftermarket Automotive Class-D Amplifier
1 Features 3 Description The TAS5414C is a four-channel Class-D audio
amplifier designed for use in automotive head units
and external amplifier modules. It provides four
channels at 23 W continuously into 4 О© at less than
1% THD+N from a 14.4-V supply. Each channel can
also deliver 38 W into 2 О© at 1% THD+N. The
TAS5414C uses single-ended analog inputs. The
class-D 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 has a
built-in load diagnostic functions for detecting and
diagnosing misconnected outputs to help to reduce
test time during the manufacturing process. Four-Channel Single-Ended Analog Input Class-D
