D2-74083-LR

Audio Special Purpose Overview

The D2-74083-LR is a System-on-Chip (SoC) digital audio processor from the Renesas D2-6 family. It integrates a configurable Digital Signal Processor (DSP) for audio signal path processing—including equalization, dynamic range compression, mixing, and filtering—and 12 integrated digital PWM controllers for Class-D amplifier control. The device supports multi-channel output configurations and features internal noise shaping, an asynchronous sample rate converter, and high-resolution operation to achieve SNR >110dB and THD+N <0.01%. It is housed in a 128-pin LQFP package.
