Within the ± 2.5 V input range, one LSB is 76.3 µV. 2See Definition of Specifications section. These specifications do not include the error contribution from the external reference. 3All specifications in dB are referred to a full-scale input FS. Tested with an input signal at 0.5 dB below full-scale unless otherwise specified. 4The maximum should be the minimum of 5.25 V and DVDD + 0.3 V. 5Tested in Parallel Reading Mode. 6With OVDD below DVDD + 0.3 V and all digital inputs forced to DVDD or DGND, respectively. 7Contact factory for extended temperature range. Specifications subject to change without notice. |
