DESCRIPTION
Configuration and Control
The TAS5414A and TAS5424A are four-channel
Channel Gains: 12-dB, 20-dB, 26-dB, 32-dB
digital audio amplifiers designed for use in automotive
head units and external amplifier modules. The
Load Diagnostic Functions:
TAS5414A and TAS5424A provide four channels at
– Output Open and Shorted Load
23 W continuously into 4
Ω at less than 1% THD+N
– Output-to-Power and -to-Ground Shorts
from a 14.4-V supply. Each channel can also deliver
38 W into 2
Ω at 1% THD+N. The TAS5414A uses
– Patented Tweeter Detection
single-ended analog inputs, while the TAS5424A
Protection and Monitoring Functions:
employs differential inputs for increased immunity to
– Short-Circuit Protection
common-mode
system
noise.
The
digital
PWM
topology of the TAS5414A and TAS5424A provides
– Load-Dump Protection to 50 V
dramatic improvements in efficiency over traditional
– Fortuitous Open Ground and Power
linear amplifier solutions. This reduces the power
Tolerant
dissipated by the amplifier by a factor of ten under
– Patented Output DC Level Detection While
typical music playback conditions. The TAS5414A
Music Playing
and
TAS5424A
incorporate
all
the
functionality
needed
to
perform
in
the
demanding
OEM
– Overtemperature Protection
applications area. They have built-in load diagnostic
– Over- and Undervoltage Conditions
functions for detecting and diagnosing misconnected
– Clip Detection
outputs to help to reduce test time during the
manufacturing process.
