2 × 1 W BTL audio ampliﬁer TDA8542

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, V

and across the

load

• Thermally protected.

APPLICATIONS

• Portable consumer products

• Personal computers

• Motor-driver (servo).

GENERAL DESCRIPTION

The TDA8542(T) is a two channel audio power amplifier

for an output power of 2 × 1 W with an 8 Ω load at a 5 V

supply. The circuit contains two BTL amplifiers with a

complementary PNP-NPN output stage and standby/mute

logic. The TDA8542T comes in a 16 pin SO package and

the TDA8542 in a 16 pin DIP package.
