Notes:

1. All Typical values are at TA = 25° C, VDD1 = 5 V, VDD2 = 5 V.

2. Beyond the full-scale input range the data output is either all zeroes or all ones.

3. Because of the switched-capacitor nature of the isolated modulator, time averaged values are shown.

4. VREF Drift vs. VDD1 can be expressed as –0.4%/V with reference to VREF.
