Hi guys, Ive really been thinking about something. The answer might be straight forward, but went through a few books, and cant seem to find a solution ... I want to set up a amplifier, with two different gains per voltage(If that makes any sense)(Or just an way to 'bias' op amps if its possible. Anyways, this is kinda what im trying to say. I have an input pin to a amplifier. This pin will be recieving from +\-250mV --> +\-1V DC. The voltage on the input pin to the amplifier will always have between those voltages on them. Now, when it gets a min voltage of 250mV, it must have a gain of 16 (so output pin should have minimum 4V DC) and then when the input to the amplifier get a max input voltage of 1V, it should have a gain of 8(So output pin should have a maximum of 8V DC) Then in between gain should be as linear as possible between the 2 limits.. Is there a way to do this with op amps? Or how is the correct way in doing this?? Dont know maybe the aswer is straight forward but cant seem to sort it out. Any help appreciated Many thanks.
