Product Description
Texas Instruments INA219AID is a precision bidirectional current monitor integrated circuit tailored for real-time current and power sensing applications. Packaged in a compact 8-pin SOIC format, it operates over a voltage supply range of 3 V to 5.5 V, making it suitable for embedded systems and power rail monitoring.
This device provides a voltage output proportional to the voltage drop across a low-value shunt resistor, enabling accurate high-current measurements. Its high common mode rejection ratio of 100 dB ensures measurement accuracy even in noisy environments.
The INA219AID supports a single current sensing channel with low supply current of only 1 mA, optimizing power consumption in sensitive applications. It operates reliably across a wide ambient temperature range from -25°C to 85°C, though it does not meet automotive standards.
Typical applications include system power monitoring, battery management, and feedback control in industrial, laboratory, and commercial electronic systems. The device's surface mount SOIC package with 8 pins facilitates easy PCB integration in compact designs.
Operates with 3 to 5.5 V supply voltage. High CMRR 100 dB for stable measurements. Low supply current of 1 mA. Compact 8-pin SOIC surface mount package. Wide operating temperature range from -25°C to 85°C. Bidirectional output for current flow monitoring.
