ANALOG CHARACTERISTICS (T
A = 25 °C; VA+, VD+ = 5 V ±5%; VREF+ = 2.5 V, VREF- = AGND,
NBV = -2.1 V, FCLK = 32.768 kHz, OWR (Output Word Rate) = 15 Sps, Bipolar Mode, Input Range = ±100 mV;
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 = LSB16 for the CS5525, and LSB20 for the CS5526.
4. Drift over specified temperature range after calibration at power-up at 25 °C.
5. See the section of the data sheet which discusses input models on page 15.
RMS NOISE (Notes 6 and 7) 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 Sps, 32.768 kHz chopping frequency is used.
Specifications are subject to change without notice.
