I was using AD847 as comparator with single supply, which doesn't work well with 0V-5V (minimum specified supply range for AD847 is -4.5V to +4.5V). Obviously it was a mistake to operate it in that range. AD847 works as comparator for me but not stable.
Is there any comparator/opamp which can be operated with single supply (0-5V)?
CIRCUIT: OPAMP as comparator.
+IN: TV Video like waveform with 0-4V amplitude.
-IN: reference DC voltage which has to be set appropriately between 0-4V
0-5V square wave.
Kindly suggest any IC with same footprint as AD847AR(8 pin SOIC) for my application?
Thank you very much. Actually I have used A847AR already in the PCB and I want to replace it with proper IC. Ad8469 is not pin compatible with AD847.
May be AD8057ARZ will do the job. I will try.
