1 The inputs are differential anti-phase. Refer to the Error! Reference source not found. 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.
10Consult sales for extended temperature range.
