2 W BTL audio amplifier

Product specification

TDA8543

FEATURES

• Flexibility in use

• Few external components

• Low saturation voltage of output stage

• Gain can be fixed with external resistors

• Standby mode controlled by CMOS compatible levels

• Low standby current

• No switch-on/switch-off plops

• High supply voltage ripple rejection

• Protected against electrostatic discharge

• Outputs short-circuit safe to ground, VCC and across

the load

• Thermally protected.

GENERAL DESCRIPTION

The TDA8543(T) is a one channel audio power amplifier

for an output power of 2 W with an 8 Ω load at a 7.5 V

supply. The circuit contains a BTL amplifier with

a complementary PNP-NPN output stage and

standby/mute logic. The TDA8543T comes in a 16 pin

SO package and the TDA8543 in a 16 pin DIP package.

APPLICATIONS

• Portable consumer products

• Personal computers

• Telephony.
