hey guys, i'm new to this forum and was wondering if someone could help me on a quick analog cct design. i have a small AC signal with a bandwidth from 0.5-120Hz approximately, and it varies in magnitude from about 0.5mV to about 2mV. i need to create an amplifier circuit to give this a gain of about 300 or so. but obviously dealing with such a small signal, i need very low noise amplifier. i was recommended the AD820, AD822 (dual), and AD824 (quad) op amps as they are apparently precision, very low noise amplifiers. can someone help me with a design of the cct, no restraints other than it is battery powered, so low power requirements would be nice. thanks in adavnce
