Precision DAC reference design for premium audio in hi-fi applications

Overview

TopologyDAC

Description

The DAC11001 audio reference design is a unique and comprehensive audio design featuring the DAC11001A and DAC11001B. The DAC11001 is a 20-bit, low-noise, ultra-high performance precision R-2R digital-to-analog converter (DAC). Delta-sigma type modulators are the most common DACs used in audio applications. Precision R-2R based DACs are generally not used in audio applications due to the additional design considerations for specific audio requirements. This reference design demonstrates the strengths and limitations of precision R-2R DACs for dynamic signal generation in the context of high- fidelity audio as an application.

Features

20-bit precision R-2R DAC for audio generation2.1VRMS line-level outputs with 108dB total harmonic distortion plus noise (THD+N)Low-noise output bufferHigh-bandwidth reference bufferUSB and TOSLINK® optical inputI2S to serial peripheral interface (SPI) conversion

Typical applications

  • AV receiver • Streaming media player • Soundbar
  • Automotive head unit
