Resolution and sampling rate are vital for DAC quality. High resolution ensures detailed output; rapid sampling rates avoid signal lag, both critical for high-fidelity audio and video reproduction.
Types of DAC Architectures
Types of DAC Architectures
Various DAC architectures exist, including binary-weighted, R-2R ladder, and sigma-delta. Each has unique trade-offs affecting accuracy, speed, and complexity, influencing their application suitability.
DACs and Quantization Noise
DACs and Quantization Noise
DACs introduce quantization noise during conversion. Advanced techniques, like noise shaping, are used in sigma-delta DACs to push noise out of the audible frequency range, improving sound quality.
Analog Reconstruction Filters
Analog Reconstruction Filters
Post-DAC analog filters are crucial. They remove high-frequency components and 'smooth out' the signal, ensuring the output closely emulates the original analog waveform.
