LTC2947 Power and Energy Monitor | DigiKey Daily

The LTC2947 is a high-precision power and energy monitor with an integrated sense resistor supporting up to ±30 A. Three internal No Latency ΔΣ™ ADCs ensure accurate measurement of voltage and current, while high bandwidth analog multiplication of voltage and current provides accurate power measurement in a wide range of applications. An internal 300 µΩ, temperature-compensated sense resistor minimizes efficiency loss and external components. The differential voltage measurement range ranges from -0.3 V to 15.5V, independent of supply voltage. All measured quantities are stored in internal registers accessible via the selectable I2C/SPI interface. Thresholds can be set for each parameter with an optional alert when a threshold is exceeded.
