Product speciﬁcation

1 W BTL audio ampliﬁer

TDA8541

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 TDA8541(T) is a one channel audio power amplifier

for an output power of 1 W with an 8

Ω load at a 5 V

supply. The circuit contains a BTL amplifier with a

complementary PNP-NPN output stage and standby/mute

logic. The TDA8541T comes in an 8 pin SO package and

the TDA8541 in an 8 pin DIP package.

APPLICATIONS

• Portable consumer products

• Personal computers

• Telephony.
