I am designing microphone preamplifier using MAX4468(MAX4468EKA - MAXIM - Linear - Amplifiers - Audio - Kynix Semiconductor (http://www.kynix.com/Detail/110525/MAX4468EKA.html)) , but the reference diagram shows output from microphone (microphone input) going to both inverting and non-inverting terminals of the device. (picture attached below). Non-inverting terminal should be connected to ground or both non-inverting and inverting terminal should be given microphone input.
The datasheet describes a point: The MAX4466/MAX4468 are decompensated for a minimum stable gain of +5V/V.
Does it means that opamp will provide inherent gain of 5, irrespective of feedback resistors.(Page 1 of datasheet)
