I am trying to make a data aquisition system that converts analog voltage to digital value by use of ADC. Since the voltage input range of ADC is limited (5V in the device I am using), but my aquisition system needs to record voltages more than this. So I would want to attenuate higher voltage and magnify the smaller voltages. So how I am thinking of op amp for the purpose. So how can I make one?
Any references are welcome.
Thank you in advance.
