D2-92633

Intelligent Digital Amplifier and Sound Processor

Product Status: Mass Production

OVERVIEW

The D2-926xx family of the DAE-3™ and DAE-3HT™ Digital Audio Engine™ devices are complete System-on Chip (SoC) multi-channel digital sound processors and Class-D amplifier controllers.

The integrated DSP provides efficient and configurable audio signal path processing including equalization, dynamic range compression, mixing, and filtering that is completely configurable via the Audio Canvas™ III high level programming interface. The integrated PWM engine supports programmable and dynamic control of audio output, enabling a variety of multi-channel output configurations and output power capacity. Internal noise shaping, an embedded asynchronous sample rate converter, dynamic level-dependent timing, and high resolution operation supports power stage audio performances with SNR >110dB and THD+N < 0.01%.

The D2-926xx devices are provided in two package and feature configurations which include the 128-pin DAE-3, and the72-pin DAE-3HT. Both the DAE-3 and DAE-3HT provide identical performance and enable an extremely flexible platform for feature rich and cost-affordable quality audio solutions, which benefit from the addition of Class-D amplifiers and DSP audio processing.

The 12 integrated digital PWM controllers can be used in a variety of multi-channel audio system configurations, supporting powered as well as line outputs. Fully protected amplifier control provides efficient and clean Class-D power output support.
