Notes: 1. Applies after a one-time self-calibration at any temperature within -40 °C ~ +85 °C.
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
thermocouples.
4. Drift over specified temperature range after calibration at power-up at 25 °C.
5. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25 °C.
6. For peak-to-peak noise multiply by 6.6 for all ranges and output rates.
7. RMS noise numbers assume continuous calibration mode is not used. In continuous calibration mode
the noise increases by a factor of two.
* Specifications are subject to change without notice.
