INA237AIDGSR, Current Sense Amplifiers 85-V, 16-bit, I2C output current/voltage/power monitor with alert 10-VSSOP -40 to 125
Semiconductors\Integrated Circuits - ICs\Amplifier ICs\Current Sense AmplifiersINA237/INA237-Q1 Current/Voltage/Power Monitors
Texas Instruments INA237/INA237-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 INA237/INA237-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.
