DESCRIPTION
The TDA2005is class B dual audio poweramplifier
in MULTIWATT packagespecifically designedfor
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 (down to 1.6Ω in
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
Flexibilityin use : bridge or stereo boosteramplifiers with or without boostrapand 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.
