ZHCSIK6C November 2017 – November 2019 ADS8166 , ADS8167 , ADS8168
PRODUCTION DATA.
The ADS816x has a precision, low-drift reference internal to the device. See the Internal Reference section for details about using the internal reference.
For best SNR performance, the input signal range must be equal to the full-scale input range of the ADC. To maximize ENOB, an external reference voltage source can be used as described in the External Reference section.
