Active-filtering circuit for audio DACs
https://www.ti.com/lit/pdf/sbaa322
Active-filtering circuit for audio DACs Design Steps 1. Select a DAC based on the needs of the application. Consider the required signal-to-noise ratio (SNR), total harmonic distortion and noise (THD+N), and supported I2S interface sample rates. While most audio DACs support rates ranging from 16kHz to 192kHz, not all support rates like 384kHz ...

3 HiFi Audio Circuit Design 3.1 DAC Circuit Design The DAC is the source of the analog audio signal chain, and the DAC is the performance bottleneck in the chain because the THD+N performance of the best DAC in the world is 10 + dB worse than the best amplifier. The DAC contains both analog and digital functional blocks and needs ultra-low ...

Digital to Analog Converters. A Digital to Analog Converter (DAC) converts a digital input signal into an analog output signal. The digital signal is represented with a binary code, which is a combination of bits 0 and 1. This chapter deals with Digital to Analog Converters in detail. The block diagram of DAC is shown in the following figure −.
