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.
