When using an external reference. With the internal reference, the input range is −0.1 V to V
See Analog Inputs section.
Linearity is tested using endpoints, not best fit.
LSB means least significant bit. With the ±2.048 V input range, 1 LSB is 62.5 μV.
See Voltage Reference Input 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.
See the Absolute Maximum Ratings section.
In wideband and warp modes. 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.
