Notes: 1. CS5320-KL and CS5322-KL are guaranteed from 0o to 70o C. CS5322-BL is guaranteed from -40o to
+85o C. CS5321-BL is guaranteed from -55o to +85o C.
2. fO = CS5322 output word rate. Refer to “CS5322 FILTER CHARACTERISTICS” on page 8 for details
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 CS5320/21 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 ±4.5 volt input to the
CS5320/21 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 ± full scale (±4.5 volts into
CS5320/21). Calibration of offsets greater than ±5% of full scale will begin to subtract from the dynamic
range.
