Specifications subject to change without notice.
(for example: AD7564AR-B). Figure 19 is an example of Biased Mode Operation.
These specifications apply with the devices biased up at 1.23 V for single supply applications. The model numbering reflects this by means of a "-B" suffix
Temperature ranges is as follows: A Version: –40 C to +85 C.
Not production tested. Guaranteed by characterization at initial product release.
