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 16 bits for the CS5531/33 and

LSB is 24 bits for the CS5532/34.

3. This 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.
