Notes: 13. 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.
14. Common-to-differential mode rejection tested with a 50 Hz, 500 mVp-p common mode sine wave
applied to the analog inputs.
15. Output impedance is primarily determined by the integrated anti-alias resistors. Value is approximate
and can vary +/- 30% depending on process parameters.
