See Analog Input section.
LSB means least significant bit. With the 0 V to 2.5 V input range, 1 LSB is 38.15 µV.
See Definitions of Specifications section. These specifications do not include the error contribution from the external reference.
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.
Parallel or serial 16-bit.
Conversion results are available immediately after completed conversion.
The max should be the minimum of 5.25 V and DVDD + 0.3 V.
In Warp mode.
With REF, PDREF and PDBUF are LOW; without REF, PDREF and PDBUF are HIGH.
With PDREF, PDBUF LOW and PD HIGH.
Impulse Mode. Tested in Parallel Reading mode.
Consult factory for extended temperature range.
