2 / 20 page 1998 Mar 25 2 Philips Semiconductors Product specification 2 × 0.7 W BTL audio amplifier 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). QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
