Clamping Amplifier

Question asked by prkarls on Apr 1, 2014

Does anyone have any ideas for an amplifier circuit that meets the following constraints:

 

Power: <10mW

 

Input Range: +/-15V

 

Gain: 1V/V, output clamped at +/-5V

 

Bias Current: <1nA.

 

Amp Noise: <2uVpp 0.1 to 10 Hz, <50nV/rthz at 1k

 

Basically i'm trying to design a low noise, low power unity gain amplifier that clamps the output at +/-5V. I don't care about anything above +/-5V, but I don't want to amplifier inputs to draw any current when the input is below +/-15V.

 

Any ideas?

Thanks!
