78M6612-IM - Brand New TERIDIAN Energy Metering
-
Description
The 78M6612-IM is an energy metering electronic component used for single-phase power and energy monitoring applications. It is a highly integrated SOC (System On Chip) featuring a 32-bit compute engine, MPU core, RTC, and flash. The patented Single Converter Technology® with a 22-bit delta-sigma ADC, 4 analog inputs, and digital temperature compensation, along with precision voltage reference, enables the component to support a wide range of power measurement applications with very few external components.
