Notes: 1. Specifications guaranteed by design, characterization, and/or test.

2. Specification applies to the device only and does not include any effects caused by external parasitic

thermocouples.

3. Drift over specified temperature range after power-up at 25 °C.

4. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25 °C.

5. For peak-to-peak noise multiply the RMS value by 6.6.

* Specifications are subject to change without notice.
