As part of the design of a LED VU meter I need to design a precision rectifier. There are plenty of circuits for this but I need a single supply version (to work on a 12V supply). There are plenty of circuits for too but they rely on a rail to rail voltage swing capable single supply op amp. There are plenty of these too but they all seem to be micro power types and they are quite expensive - over £3 for a single. What I am looking for is jelly bean op amp of this type - kind of a single rail, rail to rail swinging TL072.
Any ideas?
