See the Analog Inputs section.
2
Linearity is tested using endpoints, not best fit.
3
LSB means least significant bit. With the 0 V to 5 V input range, 1 LSB is 76.294 μV.
4
See the Terminology section. These specifications do not include the error contribution from the external reference.
5
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.
6
Parallel or serial 16 bit.
7
Conversion results are available immediately after completed conversion.
8
The maximum should be the minimum of 5.25 V and DVDD + 0.3 V.
9
In normal mode; tested in parallel reading mode.
10
In impulse mode; tested in parallel reading mode.
