Overview
INTEGRATED CIRCUITS DATA SHEET TDA8541 1 W BTL audio amplifier Product specification Supersedes data of 1997 Feb 19 1998 Apr 01 NXP Semiconductors 1 W BTL audio amplifier Product specification TDA8541 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 TDA8541(T) is a one channel audio power amplifier for an output power of 1 W with an 8 Ω load at a 5 V supply.
The circuit contains a BTL amplifier with a complementary PNP-NPN output stage and standby/mute logic.
The TDA8541T comes in an 8 pin SO package and the TDA8541 in an 8 pin DIP package.
APPLICATIONS • Portable consumer products • Personal computers • Telephony.
