See Analog Input section.

2

LSB means least significant bit. With the 0 V to 2.5 V input range, 1 LSB is 38.15 µV.

3

See Definitions of Specifications section. These specifications do not include the error contribution from the external reference.

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

In Warp mode.

9

With REF, PDREF and PDBUF are LOW; without REF, PDREF and PDBUF are HIGH.

10

With PDREF, PDBUF LOW and PD HIGH.

11

Impulse Mode. Tested in Parallel Reading mode.

12

Consult factory for extended temperature range.
