E-TDA7377

E-TDA7377 is a 2x30W dual/quad power amplifier for car radio. It is a new technology class AB car radio 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 extremely reduced component count. The on-board clip detector simplifies gain compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car.

• ST-BY function (cmos compatible), no audible pop during ST-BY operations
• Output AC/DC short circuit protection, soft short at turn-on protection
• Overrating chip temperature protection with soft thermal limiter
• Load dump voltage surge protection and very inductive loads protection
• Fortuitous open gnd, reversed battery and ESD protection
• Supply voltage range from 8V to 18V, total quiescent drain current is 150mA maximum
• Supply voltage rejection is 50dB minimum at (Rg = 0; f = 300Hz, Tamb = 25°C)
• Output offset voltage 150mV maximum at (VS = 14.4V; RL = 4ohm; f = 1KHz; Tamb = 25°C)
• Cross talk is 70dB typical at ( f = 1KHz single ended, VS = 14.4V; RL = 4ohm; f = 1KHz)
• Operating junction temperature range from -40°C to 150°C
