TLC247x differential audio filtered amplifiers

The TLC247x family from Texas Instruments is aseries of integrated circuits specifically designed to make driving a loudspeaker with an analogue or a pulse-width modulated signal as simple as possible. Practically everything is contained in these ICs to supply apower of about 500 milliwatts (peak) to a miniature 8-ohm loudspeaker. Apart from the IC, only a handful of passive parts is required.
