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 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.
