Description
The TDA7376B is a new technology dual bridge
audio amplifier in Multiwatt 15 package designed
for car radio applications. Thanks to the fully
complementary PNP/NPN output stage
configuration the TDA7376B delivers a rail-to-rail
voltage swing with no need of bootstrap
capacitors.
Differential input pairs, that will accept either
single ended or differential input signals,
guarantee high noise immunity making the device
suitable for both car radio and car boosters
applications.
The audio mute control, that attenuates the output
signal of the audio amplifiers, suppresses pop
On - Off transients and cuts any noises coming
from previous stages. The standby control, that
de-biases the amplifiers, reduces the cost of the
power switch. The on-board programmable
distortion detector allows compression facility
whenever the amplifier is over driven, so limiting
the distortion at any levels inside the presettable
range.
