2 x 1 W BTL audio amplifier with output channel switching

FEATURES:
Selection between output channelsFlexibility in useFew external componentsLow saturation voltage of output stageGain can be fixed with external resistorsStandby mode controlled by CMOS compatible levelsLow standby currentNo switch-on/switch-off plopsHigh supply voltage ripple rejectionProtected against electrostatic dischargeOutputs short-circuit safe to ground, VCC and across theloadThermally protected.

APPLICATIONS:
Telecommunication equipmentPortable consumer productsPersonal computersMotor-driver (servo).

GENERAL DESCRIPTION:
The TDA8547(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 operating condition of all channels of the device (standby, mute or on) is externally controlled by the MODE pin. With the SELECT pin one of the output channels can be switched in the standby condition. This feature can be used …
