TDA2005
20W BRIDGE AMPLIFIER FOR CAR RADIO
High output power :
P
O
= 10 + 10 W@R
L
= 2鈩?
d = 10% ; P
O
= 20W@R
L
= 4鈩?, 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.

in MULTIWATT
廬
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鈩?in
