Analog Devices Inc. LTC2947 30A Power/Energy Monitors feature an internal sense resistor supporting up to ±30A. The LTC2947 have three internal No Latency Δ∑™ ADCs to ensure accurate measurement of voltage and current. High bandwidth analog multiplication of voltage and current provides accurate power measurement in a wide range of applications. Internal or external clocking options enable precise charge and energy measurements.
