D2-92633

Intelligent Digital Amplifier and Sound Processor

Product Status: 量産中

OVERVIEW

The D2-3(S) family (D2-92633-LR, D2-92634-LR, D2-92643-LR, D2-92683-QR, D2-92684-QR) of the D2-3 and D2-3S Digital Audio Processor 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 using the D2 Audio Customization GUI v3 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 support power stage audio performances with SNR >110dB and THD+N <0.01%.

The D2-3(S) devices are provided in two package and feature configurations which include the 128 Ld D2-3 family and the 72-pin D2-3S family. Both the D2-3 and D2-3S family 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.
