Low Noise Microphone Preamplifier Circuit


Posted on Feb 6, 2014

The microphone preamplifier circuit design presented in this schematic use SSM2015 produced by Precision Monolithics Inc. (PMI) which offers a high amplification and low noise ( 1. 3nV/ f). Has been designed to work with differential input signals and can deliver 10 to 2000x amplification and it is term of R4 value. For R5 = R6 the amplification
