I stumbled on this IC while looking at possible diode replacements for the venerable 1N34-style part. I haven't thoroughly read through the spec sheet, but I wanted to put this out for general discussion and feedback. It claims to have a forward drop of less than 100mV, which would make for great sensitivity in an AM receiver. The supply voltage pin doubles as the input pin if I'm reading the sheet correctly, and the supply spec is 1.5 V or higher, so I'm not sure if it could be adapted to detector duties, but some discussion seems warranted to explore the possibility.
