The TAS5602 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 TAS5602 can drive a speaker with an impedance as low as 4Ω. The high efficiency of the TAS5602 eliminates the need for an external heat sink.

A simple interface to a digital audio PWM processor is shown below. The TAS5602 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.
