I saw this chip on a metal detector pcb.

From the Russian forum. Anyone familiar with this metal detector? Any schematics?

This is a detector from the Russian detector manufacturer "AKA". These are good detectors. The company "AKA" did not show the diagram to "Piligrim7246F". The forum md4.ru did not copy the diagram of the detector, which is why it was not published. A shipment is shown on the page, with the caveat that it may be inaccurate.
When searching the Russian site, look for topics with similar names, containing numbers close to 7246. You may find schemes that are close to what you are looking for. For example:http://www.md4u.ru/viewtopic.php?f=94&t=3301
