They perform well enough with some margin, documentation is excellent, and support is available should you need it. Chile - ENG. Modified 8 years, 9 months ago. If you need to sample audio, too, then you would need an external codec which does both - having separate ADC and DAC chips is only used in very high end applications. If one is say, looking to master or sweeten an already-recorded digital signal then investing in a really good ADC (and DAC – digital-to-analog converter) could be more practical. Application circuits for audio ADCs often have an attenuation such that full scale corresponds to that +24 dBu. I know the PCM4222 from TI, it's also a top grade ADC chip. Networking .

There are so many ways in audio ;-) Yet my interest right now is to find a way to connect this single-ended signal to a differential ADC in the - hopefully - best possible way - resembling a single-ended signal. Other ADC chips typically have only a fourth of that ripple, which is why it mostly stays invisible. A video ADC is typically 8-12 bits (sometimes 14b) and samples between 10 - 40 MHz. Nothing is oscillating. Reading raw audio values from ADC chip on raspberry pi.
