Texas Instruments TAS5601

the tas5601 is a 20-w (per channel) efficient stereo digital amplifier power stage for driving 4 single-ended speakers 2 bridge-tied speakers or combination of single and bridge-tied loads. the tas5601 can drive a speaker with an impedance as low as 4?. the high efficiency >90% into 8-? loads of the tas5601 eliminates the need for an external heat sink. a simple interface to a digital audio pwm processor is shown below. the tas5601 is fully protected against faults with short-circuit protection and thermal protection as well as overvoltage and undervoltage protection. faults are reported back to the processor to prevent devices from being damaged during overload conditions.
