DESCRIPTION

The Teridian? 78M6612 is a highly integrated, single-phase, power and energy measurement and monitoring system-onchip (SoC) that includes a 32-bit compute engine (CE), an MPU core, RTC, and flash. Our Single Converter Technology? with a 22-bit delta-sigma ADC, four analog inputs, digital temperature compensation, and precision voltage reference supports a wide range of single-phase, dual-outlet power measurement applications with very few external components.
