Dual bridge audio amplifier for car radio

Leave a Comment
Features:
Minimum external component count
No bootstrap capacitors
No Boucherot cells
Clip detector output
High output power
Fixed gain
Very low stand-by current (1 µA typ)
No switch on/off noise

Description
The TDA7374 is a class AB audio dual bridge power amplifier in Multiwatt package designed for car radio applications. Thanks to the fully complementary PNP/NPN  output configuration the high power performances  of the TDA7374 are obtained without bootstrap 
capacitors.

22 W bridge/stereo audio amplifier with clipping detector

Leave a Comment
Features:
  • Very few external components
  • No Boucherot cells
  • No bootstrap capacitors
  • High output power
  • No switch on/off noise
  • Very low standby current
  • Fixed gain (20 dB stereo)
  • Programmable turn-on delay
  • Clipping detector
  • Protections:
  • Output AC-DC short circuit to ground and to supply voltage
  • Very inductive loads
  • Loudspeaker protection
  • Overrating chip temperature
  • Load dump voltage
  • Fortuitous open ground
  • ESD

Description:

The TDA7360 is a new technology class AB Audio Power Amplifier in the Multiwatt® package designed for car radio applications. Thanks to the fully complementary PNP/NPN  output configuration the high power performance  of the TDA7360 is obtained without bootstrap  capacitors.
A delayed turn-on mute circuit eliminates audible  on/off noise, and a novel short circuit protection system prevents spurious intervention with highly  inductive loads. The device provides a circuit for the detection of  clipping in the output stages. The output, an open  collector, is able to drive systems with automatic  volume control.
