Temperature Compensation for the 71M651x/651xH, 71M652x, and 71M653x Energy Meter ICs


摘要 : Meters based on the Teridian 71M6511H, 71M6513H, 71M6533H, and 71M6534H energy-measurement ICs are expected to be accurate within 0.126% over the industrial temperature range. The 71M6511, 71M6512, 71M6521, 71M6523, 71M6531 and 71M6513 ICs provide 0.5% accuracy. The devices achieve high measurement accuracy by applying temperature- correction techniques. This application note explains how the devices can compensate for temperature effects.

The application note also examines compensation techniques for the real-time clock (RTC).
