help!
with building a circuit. i need a gain of 300 (not exact, but somewhere around there, 200-500) for a small signal (typ. 0.1mV to 5mV) AC input with a bandwidth from 0.5Hz to 120Hz. I need it low-noise, with high precision and reliability... has anyone got a reference for any sort of help to design with schematic examples etc?
I was recommended the AD820, AD822 (dual), and AD824 (quad) op amps as they are apparently precision, very low noise amplifiers. Can someone help with a circuit diagram for connecting one or several of these for the best results?
Thanks
err... and low power too... forgot about that, its going to be battery operated... if i can't get one
