1 When using an external reference. With the internal reference, the input range is 0.1 V to VREF.
3 Linearity is tested using endpoints, not best fit.
4 LSB means least significant bit. With the ±2.048 V input range, 1 LSB is 15.63 μV.
5 See Voltage Reference Input section. These specifications do not include the error contribution from the external reference.
6 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.
7 Parallel or serial 18-bit.
8 Conversion results are available immediately after completed conversion.
10 Tested in parallel reading mode.
11 With internal reference, PDREF and PDBUF are low; with external reference, PDREF and PDBUF are high.
12 With all digital inputs forced to OVDD.
13 Consult sales for extended temperature range.
