Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds op amps amplify tiny signals from sensors so analog-to-digital converters (adcs) can digitize them they also make it. High current power op amp models are available with output currents up to 30 amps and high voltage op amp models cover a range from 500 volts to 2000 volts.
