Controlling the CHOP_EN Signal

Abstract

The Teridian 71M6511, 71M6511H, 71M6513, and 71M6515H, single- and 3-phase energy-measurement ICs, offer a chopper-stabilized, analog-to-digital converter (ADC) reference that effectively eliminates drift over temperature and time. This application note describes proper control of the chopping signal through the microprocessing unit (MPU) firmware. Read full article.
