Notes: 1. Applies after system 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. LSB = LSB for the CS5525, and LSB for the CS5526.

Notes: 6. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25 °C.
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 Hz, 32.768 kHz chopping frequency is used.
Specifications are subject to change without notice.
