INTEGRATED CIRCUITS DATA SHEET TDA8547TS 2 0.7 W BTL audio amplifier with output channel switching Product specification 1998 Apr 01 Supersedes data of 1997 Oct 14NXP Semiconductors Product specification 2 0.7 W BTL audio amplifier with TDA8547TS output channel switching FEATURES GENERAL DESCRIPTION Selection between output channels The TDA8547TS is a two channel audio power amplifier for an output power of 2 0.7 W with a 16 load at a 5 V Flexibility in use supply. At a low supply voltage of 3.3 V an output power of Few external components 0.6 W with an 8 load can be obtained. The circuit Low saturation voltage of output stage contains two BTL amplifiers with a complementary PNP-NPN output stage and standby/mute logic. Gain can be fixed with external resistors The operating condition of all channels of the device Standby mode controlled by CMOS compatible levels (standby, mute or on) is externally controlled by the Low standby current MODE pin. With the SELECT pin one of the output channels can be switched in the standby condition. This No switch-on/switch-off plops feature can be used for loudspeaker selection and also High supply voltage ripple rejection reduces the quiescent current consumption. Protected against electrostatic discharge When only one channel is used the maximum output Outputs short-circuit safe to ground, V and across the power is 1.2 W. CC load Thermally protected.
