ANALOG CHARACTERISTICS (CONT.)

Notes: 14. No signals operating from external power 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

to the analog inputs.

16. Output impedance characteristics are primarily determined by the integrated anti-alias resistors. Values

are approximate and can vary up to +/- 10% depending on process parameters.
