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. LSBN: N is 16 for the CS5521/23 and N is 24 for the CS5522/24/28
4. Drift over specified temperature range after calibration at power-up at 25° C.
5. Measured with Charge Pump Drive off.
6. All outputs unloaded. All input CMOS levels and the CS5521/23 do not have a low power mode.
