DAC AC DIFFERENTIAL MODES 1, 2, 3

Notes: 20. Maximum amplitude for DAC operation above 100 Hz. A reduced amplitude for higher frequencies is

required to guarantee stability of the low-power

∆Σ DAC architecture.

21. 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.

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

amplitude.
