DESCRIPTION

The Teridian 78M6612 is a highly integrated, single-phase, power and energy measurement and monitoring SOC which includes a 32-bit compute engine (CE), an MPU core, RTC, and Flash. The Teridian patented Single Converter Technology® with a 22-bit delta-sigma ADC, 4 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.
