Product Details

Demonstration circuit 2826A features the LTC2947-65, a high precision power and energy meter with an internal 65A sense resistor. Three internal ΔΣ ADCs ensure accurate measurement of voltage (0V to 15V) and current (–65A to 65A), while high bandwidth analog multiplication of voltage and current provides accurate power measurement (–975W to 975W) in a wide range of applications. Internal or external clocking options enable precise charge and energy measurements.

Efficiency loss and external part count are minimized by an internal 150µΩ, temperature compensated sense resistor, simplifying energy measurement applications while enabling high accuracy current measurement over the full temperature range.
