Help Identifying this chip - 324

[cook]

See the attached drawing of the chip I am trying to identify. I think the last character (the 'H') may actually be the manufacturer logo, but I am not sure.

This chip is part of a hand held device that detects metal. Its called a pinpointer, and is used in the metal detecting community. The chip is located on the main power rail which is from a 9 volt battery, noted in the drawing.

I tried many searches to find the part, but did not see anything that looked close. But then I have very little experience doing this and I could have easily missed something obvious.

Single comparator of LM324 type ?

Also..... Is the 'H' with the line above it and below it actually a logo? If so, what manufacturer uses it?

Thanks mon2. I will head in that direction with my searches.

If you suspect that this chip is bad, you may be able to bypass the switch by connecting Vin to Vout. This would enable you to verify the rest of the circuit.

There is dedicated forums for metal detecting like geotech1 forum, with worldwide members with lots of information and knowledge.

When searching, first type the package name folowed with first part of marking code, in your case try: sot23-6 marking 324
Then go to image tab and look to see some pictures with 6 leg stuff with marking 324.
Last character is date manufactured or so... ignore that.
