I have been looking for and IC that can take an oscillating signal (600Hz minimum) and amplify it. Sounds easy right? Well there is a little catch… I would like to have the amplification factor adjustable via a digital signal. For example this amplifier is sent a digital signal to increase the signal multiplication factor by 1.5 each time it is pulsed. Then it can be stepped back down. I could do this with a little more complicated setup (DAC and signal multiplier) but I was hoping something already existed on a chip that could do it in one package. I need to have 36 individual controlled signal amplifiers.
Any insight or other recommendations?
