10. The upper bandwidth limit is determined by the digital filter cut-off frequency.
11. Common mode voltage is defined as the mid-point of the differential signal.
12. Dynamic Range defined as 20 log [ (RMS full scale) / (RMS idle noise) ] where idle noise is measured
13. Signal-dependent Noise defined as 20 log [ (RMS full scale) / (RMS signal noise) ] where signal noise
14. Tested with a 31.25 Hz sine wave at -1 dB amplitude and Vcm = (VA-) + 2.50V.
15. Characterized with a 31.25 Hz sine wave at -1 dB amplitude and Vcm = (VA-) + 2.35V. This
