Description
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%.
