125 and 100W Digital Audio Amplifier Power Stages

The TAS5352 and TAS5342 power stages are all pin-for-pin compatible with TI’s TAS5142DDV evaluation module, while providing additional benefits that ultimately lower system and manufacturing costs, including the following:

TI’s proprietary current-limiting circuit manages over-currents, avoiding unnecessary shutdowns and protecting against short-circuit conditions. This feature allows the power stage to drive speakers with minimum audible artifacts during high-power peaks, and reduces the possibility of device shutdown during high-level music transients. The TAS5352 and TAS5342 also allow the engineer to program the OC level to customize this setting according to the filtering inductors used. In addition, the TAS5342L provides a lower-cost alternative, offering designers another performance option for applications, based on their system performance and cost requirements.

TI’s PurePath DigitalTM Audio Technology The TAS5352, TAS5342 and TAS5342L digital amplifiers are based on TI's PurePath Digital technology, which allows consumer electronics manufacturers to build complete digital, end-to-end audio products with cutting-edge sound in a compact form factor. By reproducing movie soundtracks or music exactly the way the artist intended, PurePath Digital technology offers exceptional high-end digital entertainment to the everyday consumer. PurePath Digital technology complements other TI digital and high-performance analog products that support audio applications, such as digital signal processors (DSPs), switch mode power management, analog Class-D amplifiers and audio converters.
