Notes: 1. Dynamic range is tested with a 22 kHz input signal 60 dB below full scale.
2. Specification guaranteed by design, characterization, and/or test.
3. Full scale fully-differential input span is nominally 1.6 X the VREFIN voltage. The peak negative
excursion of the signals at AIN+ or AIN- should not go below AGND for proper operation.
4. VREFIN current is less than 1 µA under normal operation, but can be as high as ±200 µA during
calibration.
5. Drift of the on-chip reference alone is typically about ±30 ppm/°C. If using an external reference, total
full scale drift will be that of the external reference ±20 ppm/°C, which is the typical drift of the X1.6 buffer.
6. Applies after self-calibration at final operating ambient temperature.
