TDA7376PD
2 x 35 W power amplifier for car radio
Features
■ High output power capability:
– 2 x 40 W max./4
– 2 x 35 W/4 EIAJ
– 2 x 25 W/4 @14.4 V, 1 kHz, 10 %
– 2 x 25 W/2 @14.4 V, 1 kHz, 10 %
■ 2 driving
■ Differential inputs
■ Minimum external components count
■ Internally fixed gain (26 dB)
■ Mute function (CMOS compatible)
■ Automute at minimum supply voltage detection
■ Standby function
■ No audible pop during mute and standby
operations
■ Clipping detector with programmable distortion
threshold
■ Protections:
– Short circuit (out to ground, out to supply
voltage, across the load)
– Overrating chip temperature with soft
thermal limiter
– Load dump voltage
– Fortuitous open ground
– Loudspeaker DC current
– ESD

Description
The TDA7376PD is a new technology dual bridge
audio amplifier in PowerSO36 package designed
for car radio applications.
Thanks to the fully complementary PNP/NPN
output stage configuration the TDA7376PD
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 overdriven, so limiting
the distortion at any levels inside the presettable
range.
