2 / 20 page 1998 Apr 01 2 Philips Semiconductors Product specification 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, VCC 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.
