ST’s precision operational amplifier portfolio includes several series covering different voltage ranges, as well as many possible combinations of power consumption and gain bandwidth. It allows you to get the best performance for the appropriate accuracy.
ST’s precision op amp solutions include zero drift amplifiers and amplifiers with a low offset drift over temperature. Thus the precision op amps from ST are a perfect fit for use with any sensor, including gas, temperature, pressure, and position sensors. Moreover, the rail-to-rail input and output feature allows easy and accurate high-side and low-side sensing.
