Op Amp Precision Positive & Negative Clipper using LT6015/LT6016/LT6017

Tom Mosteller - Field Applications Engineer
Aaron Schultz - Applications Manager Signal Conditioning
Oct 3rd 2016
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 can flow into the ADC which can cause latch up ...
