See section. Analog Input
2
LSB means least significant bit. With the 0 V to 2.5 V input range, 1 LSB is 38.15 µV.
3
See section. These specifications do not include the error contribution from the external reference. Definitions of Specifications
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 16-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
With REF, PDREF and PDBUF are LOW; without REF, PDREF and PDBUF are HIGH.
9
With PDREF, PDBUF LOW and PD HIGH.
10
Tested in Parallel Reading Mode
