2. Specifications guaranteed by design, characterization, and/or test.
3. Specification applies to the device only and does not include any effects by external parasitic
4. Drift over specified temperature range after calibration at power-up at 25 °C.
5. See the section of the data sheet which discusses input models on page 15.
7. For Peak-to-Peak Noise multiply by 6.6 for all ranges and output rates.
8. For input ranges <100 mV and output word rates >60 Sps, 32.768 kHz chopping frequency is used.
