1See Analog Input section.
2LSB means least significant bit. With the 0 V to 2.5 V input range, 1 LSB is 38.15 µV.
3See the Definitions 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.
5Parallel or Serial 16-Bit.
6Conversion 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.
11Consult factory for extended temperature range.
