Other Parts Discussed in Thread: OPA197, OPA206
Tool/software:
Hi Experts,
Can you assist this query from customer?
They are in process of finding alternate for OP747ARZ (which is our current part). I found OPA4197ID (Texas part) as alternate, as in their existing design they have single source from 0 to 5V supply voltage, High pass RC filter (basically a differentiator) input to non-inverting pin, they see negative spikes with magnitude of around -4V at input (non-Inverting).
As datasheet says from absolute maximum rating Input voltage = –VS – 5 V to +VS + 5 V. Which means Input can withstand negative spikes even with single supply (0 to 5V) is this correct?
Query:
We would like to know whether the alternate part will withstand negative spikes even when it operates with single supply from 0 to 5V? As datasheet says Rail to Rail Input, correct me if I'm wrong Input can withstand negative spikes only when it operates with dual supply but not with single supply or the other way around where input can still withstand negative spikes even when it operates with single supply?
Thank you.
Regards,
Archie A.
