Analog Inputs
2
LSB means Least Significant Bit. With the ±4.096 V input range, 1 LSB is 31.25 μV.
3
See
section. The nominal gain error is not centered at zero and is +0.273% of FSR. This specification is the deviation from this nominal
value. These specifications do not include the error contribution from the external reference, but do include the error contribution from the reference buffer if used.
4
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.
5
Parallel or Serial 18-Bit.
6
Conversion results are available immediately after completed conversion.
7
The max should be the minimum of 5.25 V and DVDD + 0.3 V.
8
Tested in Parallel Reading mode.
9
Contact factory for extended temperature range.
