Notes: 13. Ratio of common mode input amplitude vs. differential mode output amplitude for a perfectly matched
common mode input signal. Characterized with a 50 Hz, 500 mV_peak common mode sine wave applied
to the analog inputs.
14. Output impedance characteristics are approximate and can vary up to +/- 30% depending on process
parameters.
