Overview

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 generation
  • 2.1VRMS line-level outputs with 108dB total harmonic distortion plus noise (THD+N)
  • Low-noise output buffer
  • High-bandwidth reference buffer
  • USB and TOSLINK® optical input
  • I2S to serial peripheral interface (SPI) conversion
