Texas Instruments TAS5086DBT

Description
The TAS5086 is a sixchannel PWM processor that provides a complete audio signal path from input to output. It features four serial audio inputs, six PWM audio output channels, and a variety of audio processing features, including volume control, bass management, and deemphasis. The TAS5086 is ideal for use in a variety of audio applications, including home theater systems, soundbars, and portable speakers.
