Summary

With reduced size, increased accuracy, and easy integration, the AMC038x product family is a potent design for a variety of applications. The integrated high voltage resistor enables industry leading accuracy of <1%, a 50% smaller PCB design size, and removes the need for end of line calibrations. Such improvements bolster the ability of these isolated amplifiers and modulators to be well suited for HEV, energy infrastructure, and motor drive applications.
