on the FIR Filter.
3. Characterized with full scale input signal of 50 Hz; fo = 500 Hz.
4. Characterized with input signals of 30 Hz and 50 Hz, each 6 dB down from full scale with fo = 1000 Hz.
5. Specification is for the parameter over the specified temperature range and is for the CS5321 device
only (VREF = +4.5 V). It does not include the effects of external components; OFST = 0.
6. Drift specifications are guaranteed by design and/or characterization.
7. The offset after calibration specification applies to the effective offset voltage for a
卤4.5
volt input to the
CS5321 modulator, but is relative to the output digital codes from the CS5322 after ORCAL and USEOR
have been made active.
8. The CS5322 offset calibration is performed digitally and includes
卤
full scale (卤4.5 volts into CS5321).
Calibration of offsets greater than
卤5%
of full scale will begin to subtract from the dynamic range.
