ADE7569ASTZF16 - Brand New Analog Devices Energy Metering
-
GENERAL DESCRIPTION
The ADE7757 is a high accuracy electrical energy measurement IC. It is a pin reduction version of the ADE7755 with an enhancement of a precise oscillator circuit that serves as a clock source to the chip. The ADE7757 eliminates the cost of an external crystal or resonator, thus reducing the overall cost of a meter *U.S. Patents built with this IC. The chip directly interfaces with the shunt resistor and operates only with ac input.
