DESCRIPTION
The TDA7376B is a new technology dual bridge
Audio Amplifier in Multiwatt 15 package designed
for car radio applications. Thanks to the fully com-
plementary 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 im-
munity making the device suitable for both car ra-
dio and car boosters applications.
The audio mute control, that attenuates the out-
put signal of the audio amplifiers, suppresses pop
on - off transients and cuts any noises coming
from previous stages. The St-By control, that de-
biases the amplifiers, reduces the cost of the
power switch. The on-board programmable distor-
tion detector allows compression facility when-
ever the ampifier is overdriven, so limiting the dis-
tortion at any levels inside the presettable range.
