Description

This 2.1 Audio Amplifier solution is designed for applications requiring 10 watts or less output power where the addition of a mono subwoofer can enhance the sound quality of stereo audio systems. A stereo TAS5756M Class-D IC amplifier is implemented for the left and right audio channels and a TAS5760M Class-D amplifier provides a mono bass channel. Biquad filters, dynamic bass enhancement and other miniDSP processing blocks allows for a fully tunable 2.1 design for integration into nearly any audio system and application. The TAS5756M output filter has been designed for small footprint allowing easy adaptation into sound bars and Bluetooth speakers where small solution size and cost are critical.

Features
  • Next generation closed loop mid power amplifier boosts excellent audio performance
  • PurePath HybridFlow Processing enhances the sound of small-to-mid size speakers
  • 10W Class-D output for high efficiency from 12V supply
  • Inductor free (ferrite bead) filter for TAS5756 stereo channels reduces 2.1 system cost and footprint
  • Connection to host computer via motherboard allows for design evaluation
  • System input from digital audio sources
