With the ±2.5 V input range, one LSB is 76.3 µV. 2In Warp Mode. 3Tested with VREF = 2.5 V. See Definition of Specifications section. These specifications do not include the error contribution from the external reference. 4All 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. 5The max should be the minimum of 5.25 V and DVDD + 0.3 V. 6Tested in Parallel Reading Mode. 7In Impulse Mode. 8With OVDD below DVDD + 0.3 V and all digital inputs forced to DVDD or DGND, respectively. 9Contact factory for extended temperature range.
