IDT's family of metering ICs for smart power meters in the smart grid industry feature the widest dynamic range in the industry as well as extremely high accuracy, helping to improve the performance of smart meters. The new IDT metering solutions feature a wide dynamic range of 5000:1, allowing manufacturers to merge the various types of meters currently available, such as 5(20)A, 10(40)A, 15(60)A and 20(80)A, into one standard model (5(100)A or 1(100)A), simplifying the manufacturing process and reducing the overall bill of materials.

Single-Phase Metering IC
The IDT90E21/22/23/24 is a high-performance energy metering device for single-phase two-wire, single-phase three-wire or electricity meters with anti-tampering mode. With the measurement function, the 90E21/22/23/24 series can also be used in power instruments which need to measure voltage, current, etc.
