The AD8307 is a logarithmic amplifier normally used for RF power measurments, but it can also be used as an audio milli/micro voltmeter.
Does anyone knows how to configure the input stage for LF audio applications ? The one shown on the application sheet from Analog Devices, seems to have some errors. I have this circuit, but it is too complicated, I want something simpler.
