Product Summary

The ADE7757ARN is a high accuracy electrical energy measurement IC. It is a pin reduction version of the AD7755 with an enhancement of a precise oscillator circuit that serves as a clock source to the chip. The ADE7757ARN eliminates the cost of an external crystal or resonator, thus reducing the overall cost of a meter bulit with this IC.
