Delta Sigma ADC Performance Calculator
The tool calculates ideal single loop multilevel quantizer ADC quantization error power and dynamic range from full scale signal power, signal bandwidth, sampling rate, quantizer levels, and order of the Delta-Sigma ADC. The calculation assumes that the quantization noise is white and bandwidth of signal << sampling frequency. Stability constraint on higher order single loop delta-sigma will cause the ADC to operate at lower dynamic range than what is calculated.
