Notes: 14. No signal sources operating from external supplies should be applied to pins of the device prior to its
own supplies being established. Connecting any terminal to voltages greater than VA+ or less than VA-
may cause destructive latch-up.
15. 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.
16. Output impedance characteristics are primarily determined by the integrated anti-alias resistors. Values
are approximate and can vary +/- 10% depending on process parameters.
