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
