Product Summary
The TDA8547TS is a two channel audio power amplifier for an output power of 2×0.7W with a 16W load at a 5 V supply. At a low supply voltage of 3.3 V an output power of 0.6 W with an 8Ω load can be obtained. The TDA8547TS 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 for loudspeaker selection and also reduces the quiescent current consumption. When only one channel is used the maximum output power is 1.2W. The applications of the TDA8547TS include Telecommunication equipment, Portable consumer products, Personal computers, Motor-driver (servo).
