Integrated Device Technology (IDT) has announced a new family of poly-phase power metering ICs that offer the widest dynamic
range and lowest temperature coefficient in the industry. These new devices allow smart energy meter manufacturers to increase performance while consolidating functionality and lowering cost. The poly-phase power metering ICs expand on IDT’s award-winning 90E2x family of single-phase devices.
The 90E32 and 90E36 poly-phase metering ICs feature the industry’s widest dynamic range of 5000:1 (90E32) and 6000:1 (90E36), and the lowest temperature coefficient with proprietary temperature compensation technology, offering superior performance over a wide range of usage patterns and environmental conditions, increasing flexibility for meter manufacturers.
In addition, the IDT 90E36 features an on-chip Discrete Fourier Transform (DFT) analysis engine with Total Harmonic Distortion (THD) detection, raw analog to digital converter (ADC) data access via a direct memory access (DMA) port and other versatile parameter measurement functions.
