Q
Please provide details (schematics) about the 10V analog input. Most importantquestion: is there any kind of protection device at the input (e.g. clamp
diodes to the supplies) or does the input directly connect to the 5k (nom.)
resistor?
A
The 10V analog input connects directly to the 5k (thin film) resistor. Theprotection diodes are after the input resistor as per figure 2 in the
datasheet.
We do not have a max rating for the 10V input on the datasheet, however as the
20V input has a max rating of +/-24V independent of the power supply, you can
assume the 10V input has a +/-10V max ratings when unpowered. Voltage
excursions slightly above +/-10V are unlikely to damage the part but as this is
not explicitly tested, we cannot guarantee.
