3 Description
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.
