AD7675–SPECIFICATIONS
LSB means Least Significant Bit. With the ± 2.5 V input range, one LSB is 76.3 µV.
See Definition of Specifications section. These specifications do not include the error contribution from the external reference.
All 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.
The max should be the minimum of 5.25 V and DVDD + 0.3 V.
Tested in Parallel Reading Mode.
With OVDD below DVDD + 0.3 V and all digital inputs forced to DVDD or DGND, respectively.
Contact factory for extended temperature range.
