When using an external reference. With the internal reference, the input range is from −0.1 V to V
See the Analog Inputs section.
Linearity is tested using endpoints, not best fit. Tested with an external reference at 2.048 V.
LSB means least significant bit. With the ±2.048 V input range, 1 LSB is 62.5 μV.
See the Terminology section. These specifications do not include the error contribution from the external reference.
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.
Parallel or serial 16-bit.
Conversion results are available immediately after completed conversion.
See the Absolute Maximum Ratings section.
Tested in parallel reading mode.
With internal reference, PDREF and PDBUF are low; without internal reference, PDREF and PDBUF are high.
With all digital inputs forced to OVDD.
Consult sales for extended temperature range.
