See the Analog Inputs section.
Linearity is tested using endpoints, not best fit.
LSB means least significant bit. With the 0 V to 5 V input range, 1 LSB is 76.294 μV.
See the Terminology section. These specifications do not include the error contribution from the external reference.
All specifications in dB are referred to as 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.
The maximum should be the minimum of 5.25 V and DVDD + 0.3 V.
In normal mode; tested in parallel reading mode.
In impulse mode; tested in parallel reading mode.
Consult sales for extended temperature range.
