INA239/INA239-Q1 Current/Voltage/Power Monitors

Texas Instruments INA239/INA239-Q1 Current/Voltage/Power Monitors are ultra-precise digital power monitors with a 16-bit delta-sigma ADC specifically designed for current-sensing applications. The device can measure a full-scale differential input of ±163.84mV or ±40.96mV across a resistive shunt sense element with common-mode voltage support from –0.3V to +85V. The INA239/INA239-Q1 reports current, bus voltage, temperature, and power, all while performing the needed calculations in the background. The integrated temperature sensor is ±1°C accurate for die temperature measurement and is useful in monitoring the system’s ambient temperature.
