Flexibility in use : bridge or stereo booster amplifi-
ers with or without boostrap and with programma-
ble gain and bandwidth.
Space and cost saving : very low number of exter-
nal components, very simple mounting system with
no electrical isolation between the package and the
heatsink (one screw only).
In addition, the circuit offers loudspeaker protec-
tion during short circuit for one wire to ground.

ORDERING NUMBERS : TDA2005M (Bridge Appl.)
DESCRIPTION
The TDA2005 is 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 (down to 1.6
