3. Specification is for the parameter over the specified temperature range for the CS5371/72 devices only
and does not include the effects of external components.
4. Specifications are guaranteed by design and/or characterization.
5. The offset after calibration specification applies to the effective offset voltage for a full-scale input to the
CS5371/72 modulator, but is measured from the output digital codes from the digital filter.
6. The CS5371/72 offset calibration is performed digitally and includes the full-scale range.
