INA250A4PWR

The Texas Instruments INA250A4PWR is a voltage-output, current-sensing amplifier that integrates a precision 2 mΩ shunt resistor. This device enables high-accuracy current measurements at common-mode voltages ranging from -0.1 V to 36 V, independent of the supply voltage. It functions as a bidirectional, low- or high-side current-shunt monitor.

Key electrical specifications include a maximum common-mode voltage of 36 V, a minimum of 0 V, and a wide common-mode range of -0.1 V to 36 V. The INA250A4 variant offers a gain of 2 V/A with a maximum gain error of 0.3%. The integrated shunt resistor has a tolerance of 0.1% and a temperature coefficient of 10 ppm/°C. The operating temperature range is specified from -40°C to 125°C.

Packaged in a 16-pin TSSOP, the INA250A4PWR is suitable for applications requiring precise current monitoring. Its integrated shunt resistor simplifies design and reduces component count. The amplifier's bidirectional capability allows for measurement of both positive and negative current flows.

This current sense amplifier is designed for various applications including power management, battery monitoring, and motor control systems where accurate current feedback is critical. The device's high accuracy and wide operating range make it a versatile solution for demanding designs.
