REV. B
LSB means least significant bit. With the ±5 V input range, one LSB is 152.588 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.
Tested with the 0 V to 5 V range and V
With OVDD below DVDD + 0.3 V and all digital inputs forced to DVDD or DGND, respectively.
Contact factory for extended temperature range.
Typical analog input impedance.
With REF = 3 V, in this range, the input should be limited to –11 V to +12 V.
For this range the input is high impedance.
