section.
2
Linearity is tested using endnotes, not best fit.
3
LSB means least significant bit. With the 0 to 5V input range, 1 LSB 38.15μV.
4
All specifications in dB are referred to a full-scale input FSR. Tested with an input signal at 0.5 dB below full-scale, unless otherwise specified.
5
Parallel or serial 18-bit.
6
Conversion results are available immediately after completed conversion.
7
Tested in parallel reading mode.
8
With internal reference, PDREF and PDBUF are low; without internal reference, PDREF and PDBUF are high.
9
With all digital inputs forced to OVDD.
10
Consult sales for extended temperature range.
