& DGND= 0V;VREF+ = 4V, VREF- = -4 V; MCLK frequency as noted.)

Notes: 1. Full scale current is tested under two conditions: CAPSIZE = 0 (CDAC = 1.6 pF) with MCLK at 1.024

MHz and CAPSIZE = 1 (CDAC = 4.8 pF) with MCLK at 2.048 MHz. Dynamic Range (Signal-to-Noise) is

tested with 101 Hz sine wave voltage driven into a 5 M

Ω input resistor with a 470 pF capacitor connected

from INR or INL to REFGNDR or REFGNDL respectively, to test each modulator. S/N and integral

nonlinearity are tested with CAPSIZE = 0 (CDAC = 1.6 pF) with MCLK at 2.048 MHz and CAPSIZE = 1

(CDAC = 4.8 pF) with MCLK at 1.024 MHz.

2. Guaranteed by design or characterization.

3. Specification applies after a complete calibration sequence using the CS5542/CS5543 combination. Drift

specification is for the CS5542/CS5543 only and does not include drift due to the input components, the

VREF voltage, or a frequency change of CLKIN.

4. Specification applies only to System Offset Calibration using the CS5542/CS5543 chip combination after

Input Offset Voltage calibration has been completed with no external offset applied to the input.

5. The VA+ and VA- supplies should be quiet supplies (see data sheet text). Power supply sequence is

important. The VA+ and VA- supplies should be applied to the CS5542 prior to or at the same time as

the VD+ supply.

6. Power supply rejection is tested with a 100 mVp-p sine wave applied to each supply. See data sheet

text for power supply noise requirements.
