AC DIFFERENTIAL MODES 1, 2, 3

Notes: 10. Maximum amplitude for operation above 100 Hz. A reduced amplitude for higher frequencies is required

to guarantee stability of the low-power delta-sigma architecture.

11. Full-scale accuracy compares the defined full-scale 1/1 amplitude to the measured 1/1 amplitude.

Specification is for unloaded outputs. Applying a differential load lowers the output amplitude ratiometric

to the differential output impedance.

12. Relative accuracy compares the measured 1/2,1/4,1/8,1/16,1/32,1/64 amplitude to the measured 1/1

amplitude.

13. Common mode voltage is defined as [(SIG+) + (SIG-)] / 2.

14. Specification is for the parameter over the specified temperature range and is for the device only. It does

not include the effects of external components.
