INA219 has the industry's highest\nprecision and small size, can not only monitor the pressure drop on the shunt\nresistor, detect the shunt power supply voltage, but also calculate the power\nat the same time. The device features SOT23 packaging, but for the server,\nnotebook computer and power supply, battery management and digital electric\nvehicle and telecommunications devices for measuring flu offer small, cost-\neffective solutions. INA219-40°C to +85°C temperature range and can realize\nthe maximum error of 1% accuracy, maximum offset of 100uV. The advantage of\nthe high precision of the product combined with the 12 resolution can help\nreduce the pressure drop at the shunt resistor, which can minimize power loss\nand power consumption and save board space. The device has a 26 bus voltage\nrange from 0V to +26V. The programmable INA219 calibration registers can be\nread directly. The unit of measurement is the amp current and the power in\nwatts per read. for up to 128 sampling averages to realize filters in noise\nenvironments. The I2C interface has a timeout, which can not only avoid bus\nlock, but also provide a high-speed mode that meets the communication\nrequirements of up to 3.4 MHz. All functions are programmable by the software\nINA219. When using a single power supply, the working voltage is between +3.0\nand +5.5V.
