Notes: 1. Applies after system calibration at any temperature within -40 °C ~ +85 °C.

2. Specifications guaranteed by design, characterization, and/or test. LSB is 24 bits.

3. This specification applies to the device only and does not include any effects by external parasitic

thermocouples. The PGIA contributes 5 nV of offset drift, and the modulator contributes 640/G nV of

offset drift, where G is the amplifier gain setting.

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