    The SY7T6xx/SY7T6xxE are energy measurement processors (EMPs) with up to six analog (sense) inputs. They are ideally suited for embedded poly-phase or power distribution applications.

    The analog front end (AFE) provides analog (sense) inputs for interfacing with up to six current or voltage sensors. Scaled voltages from the sensors are fed to a high-resolution delta-sigma converter. A low power 24-bit energy measurement processor (EMP) with embedded firmware performs all the necessary computation, compensation, and data formatting. With integrated flash memory for storing nonvolatile data such as calibration coefficients and device configuration settings, the SY7T6xx/SY7T6xxE provide an autonomous solution that simplifies system integration.
