Op Amps Make Precision Clipper, Protect ADC (.PDF Download)

It can be a challenge to match the voltage range of an analog signal to the input range of an analog-to-digital converter (ADC). Exceeding the ADC’s input range will give an incorrect reading. And if the input goes far enough beyond the power-supply rails, substrate currents may flow into the ADC, which can then cause latch up or even damage to the part. However, restricting the input-voltage range to lower, more-conservative levels wastes the ADC’s dynamic range and resolution...
