Notes: 13. Ratio of input common mode amplitude vs. output differential mode amplitude for a perfectly matched

common mode input signal. Characterized with a 50 Hz, 500 mVpeak 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.
