Circuit power amplifier 20w Bridge amplifier for car audio with Tda 2005

DESCRIPTION
The TDA2005is class B dual audio power amplifier in MULTIWATT package specifically designed for car radio application : power booster amplifiers are easily designed using this device that provides a high current capability (up to 3.5 A) and that can drive very low impedance loads.

High output power : PO = 10 + 10 W@RL =2Ω, d = 10% ; PO = 20W@RL =4Ω ,d=1%.
High reliability of the chip and package with additional complete safety during operation thanks to protection against :

  • Output dc and ac short circuit to ground
  • Overrating chip temperature
  • Load dump voltage surge
  • Fortuitous open ground
  • Very inductive loads

Flexibility in use : bridge or stereo booster amplifiers with or without boostrap and with programmable gain and bandwidth.
Space and cost saving : very low number of external components, very simple mounting system with no electrical isolation between the package and the heatsink (one screw only).
In addition, the circuit offers loudspeaker protection during short circuit for one wire to ground.
