20W STEREO (BTL) DIGITAL AMPLIFIER POWER STAGE

DESCRIPTION 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. By Texas Instruments
