TYPICAL RMS NOISE, CS5521/23
Notes: 10. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25° C.
TYPICAL NOISE FREE RESOLUTION (BITS), CS5521/23
Notes: 13. For bipolar mode, the number of bits of Noise Free Resolution is LOG((2XInput Range)/(6.6xRMS

11. To estimate Peak-to-Peak Noise, multiply RMS noise by 6.6 for all ranges and output rates.
12. For input ranges <100 mV and output rates ≥60 Sps, 16.384 kHz chopping frequency is used.
Noise))/LOG(2) rounded to the nearest bit. For unipolar mode, the number of bits of Noise Free
Resolution is LOG((Input Range)/(6.6xRMS Noise))/LOG(2) rounded to the nearest bit. Also, the
CS5521/23’s output conversions are 16 bits. Noise free Resolution numbers are based upon
VREF = 2.5 V and XIN = 32.768 kHz. The values will be affected directly by changes in VREF, but the
effects due to changes in the XIN frequency will be minor.
