Philips Semiconductors
2 W BTL audio amplifier
Product specification
TDA8543
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_CC and across
the load
• Thermally protected.
GENERAL DESCRIPTION
The TDA8543(T) is a one channel audio power amplifier
for an output power of 2 W with an 8 Ω load at a 7.5 V
supply. The circuit contains a BTL amplifier with
a complementary PNP-NPN output stage and
standby/mute logic. The TDA8543T comes in a 16 pin
SO package and the TDA8543 in a 16 pin DIP package.
APPLICATIONS
• Portable consumer products
• Personal computers
• Telephony.
