13. Common mode voltage is defined as the mid-point of the differential signal.
14. Dynamic Range defined as 20 log [ (RMS full scale) / (RMS idle noise) ] where idle noise is measured
15. Signal-dependent Noise defined as 20 log [ (RMS full scale) / (RMS signal noise) ] where signal noise
16. Tested with a 31.25 Hz sine wave at -1 dB amplitude.
17. Specification is for the parameter over the specified temperature range and is for the device only. It does
18. Specification applies to the effective offset voltage calculated from the output codes of the CS5378
19. Offset calibration is performed in the CS5378 digital filter and includes the full-scale signal range.
