Other Parts Discussed in Thread: ADS1281
The ADS1282-SP ABS max specifications indicate "100mA momentary" and "10mA continuous" limits for input current.
1. What input current is this referring to? Avdd? Analog inputs? Digital inputs? what about AVSS?
2. Is this current specified into/out of any one pin at a time or is it for a group of pins?
3. The Power Supply Electrical characteristics indicate 11mA max for AVDD - How can the part be used in this mode if the ABS max is 10mA continuous?
4. What is meant by "momentary" and "continuous" in the context of the ABS max ratings?
This information is needed to perform a worst-case analysis stress analysis.
Thanks!
