The Texas Instruments INA219 is a versatile current shunt and power monitor designed for applications requiring precise measurement of voltage, current, and power. It utilizes an I2C or SMBUS-compatible interface, making integration into digital systems straightforward. The device can sense bus voltages ranging from 0 to 26 V and reports current, voltage, and calculated power.
Key features include a programmable calibration value for direct current readouts in amperes and a multiplying register for power calculations in watts. The INA219 offers 16 programmable addresses, allowing multiple devices on the same bus. It is available in SOT23-8 and SOIC-8 packages, supporting surface mount applications.
With a wide operating temperature range of -40°C to 125°C, the INA219 is suitable for demanding environments. The device draws a maximum of 1 mA of supply current from a 3- to 5.5-V supply. The INA219B grade offers higher accuracy, with a maximum error of 0.5% over temperature.
