Introduce this Module:
The TDA7377 is a new technology Class AB car amplifier able to work either in DUAL BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with the extremely reduced component count. The on-board IC detector simplifies gain compression operation.
Some Core Parameters of the Module:
SPECIAL FEATURES :
● High Output Power Capability: 2 Speakers35W max./4Ω.
● ST-By Function (CMOS Compatible).
● NO Audible Pop During ST-By Operations.
● Internally Fixed Gain (26dB BTL).
● Diagnostics Facility for Out to GND Short or Out to Vs.
ABSOLUTE MAXIMUM RATINGS:
● Operating Supply Voltage 18V.
● DC Supply Voltage 28V DC.
● Peak Power Supply Voltage (for time = 50ms)
● Output Peak Current (not repetitive time = 100μs)
● Output Peak Current (repetitive Frequency > 10Hz)
● Temperature Storage and Junction : -40 to 150℃

Class AB Power Amplifier
Class AB amplifiers are a combination of class A & class B amplifiers. This class of amplifiers is designed to reduce the less efficiency problem of class A amplifiers and distortion of the signal at the crossover region in class B amplifiers.
It maintains high-frequency response like in class A amplifiers and very good efficiency as in class B amplifiers.
A combination of diodes and resistors are used to provide little voltage which reduces the distortion of waveform near the crossover region. There is a little drop in efficiency of 60%.
