ANALOG CHARACTERISTIC (Cont.)

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.
