2 × 1.5 W BTL audio amplifier

Product specification

TDA8542AT

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 TDA8542AT is a two channel audio power amplifier

for an output power of 2 × 1.5 W with an 8 Ω load at a 6 V

supply. The circuit contains two Bridge-Tied Load (BTL)

amplifiers with a complementary PNP-NPN output stage

and standby/mute logic. The TDA8542AT comes in a

20-pin SO package.

APPLICATIONS

• Portable consumer products

• Personal computers

• Motor-driver (servo).
