TDA8542TS

2 x 0.7 W BTL audio amplifier

Philips Electronics 

Philips Semiconductors

2 × 0.7 W BTL audio amplifier

Product specification

TDA8542TS

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 TDA8542TS is a two channel audio power amplifier

for an output power of 2 × 0.7 W with a 16 Ω load at a 5 V

supply. At a low supply voltage of 3.3 V an output power of

0.6 W with an 8 Ω load can be obtained. The circuit

contains two Bridge-Tied Load (BTL) amplifiers with a

complementary PNP-NPN output stage and standby/mute

logic. The TDA8542TS is available in a SSOP20 package.

APPLICATIONS

• Portable consumer products

• Personal computers

• Motor-driver (servo).
