ORDERING NUMBERS : TDA2005M (Bridge Appl.)
TDA2005S (Stereo Appl.)
®
High output power : PO = 10 + 10 W@RL =2
Ω,
d = 10% ; PO = 20W@RL =4
Ω ,d = 1 %.
High reliability of the chip and package with addi-
tional 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 ampli-
fiers with or without boostrap and with programma-
ble gain and bandwidth.
Space and cost saving : very low number of
external components, very simple mounting sys-
tem with no electrical isolation between the pack-
age and the heatsink (one screw only).
In addition, the circuit offers loudspeaker protec-
tion during short circuit for one wire to ground.
DESCRIPTION
The TDA2005 is class B dual audio power amplifier
in MULTIWATT
® packagespecifically 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
Ω in
