DATASHEET Intelligent Digital Amplifier PWM Controller and Audio
Processor
D2-41051, D2-41151 Features The D2-41051 and D2-41151 (D2-41x51-QR) devices are
complete System-on-Chip (SoC) Audio Processor and Class-D
Amplifier Controllers, offering a powerful yet very cost effective
audio solution for high volume consumer products, including
Digital TV systems, PC Multimedia Speakers, and Portable
Device Docking Stations. This 4th generation Digital Audio
Engine (DAE-4)в„ў device combines extensive integrated DSP
processing and configurable audio processing algorithms, for
complete audio system control. The D2-41x51-QR devices are
built upon the proven technology present in D2Audio's D2-814xx,
D2-914xx, and D2-926xx families of Class-D Controller ICs, while
providing an optimized feature set for high volume and
cost-critical products. All Digital Class-D Amplifier Controller with Integrated Digital
Signal Processing (DSP) The D2Audio D2-41x51-QR devices offer the optimum balance of
functionality and lowest system material cost, especially in an
SoC system architectures with I2S audio output. All audio
processing and amplifier control is handled by the D2-41x51-QR,
and its ease of integration to the existing system processor
handles all system control functions. Supports 2.0, 2.1 or Bi-Amp Amplifier Outputs with Discrete or
Integrated Power Stages Fully Programmable Audio Signal Path Parameters Up to 5 Channels of Digital Signal Processing (DSP) Includes Equalizers, Filters, Mixers and Other Common Audio
Processing Blocks Audio Enhancement Algorithms Included I2S and S/PDIFв„ў Digital Audio Stereo Inputs I2C Host Control Port Asynchronous Sample Rate Converters, Sample Rates from …
