Controlling the CHOP_EN Signal


摘要 : 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.
