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 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).
