Programming temperature for AD8556 and AD8557

Question asked by romann on Nov 9, 2012

Hello,

 

The datasheet for both AD8556 and AD8557 states that, when programming the device, its temperature must remain between 10 and 40 deg C. I have two questions regarding this:

 

1. Can this constraint be overcome (e.g., by adjusting the pulse widths and/or the intervals between pulses on the DIGIN pin)?

 

2. The datasheet for AD8555 does not appear to specify any programming temperature range.  Is this device actually more temperature-tolerant?

 

Many thanks,

 

-Roman
