Introduction Delta-sigma analog-to-digital converters (ADCs) are oversampling ADCs: to reduce noise and analog front-end circuit cost and complexity, they sample signals at very high rates and produce a low-noise, high-resolution output.
Oversampling at a “high” rate means sampling a signal at a frequency that is well above the bandwidth of interest’s Nyquist rate and is done to lower in-band noise.
The output word rate of the ADC will be close to the bandwidth of interest.
