INA250A1PW Description

Short technical summary and product information.

The Texas Instruments INA250A1PW is a voltage-output, current-sensing amplifier that integrates a precision shunt resistor. This device enables high-accuracy current measurements at common-mode voltages ranging from -0.1V to 36V, independent of the supply voltage.

Key electrical specifications include a maximum common-mode voltage of 36V, a minimum common-mode voltage of 0V, and a wide common-mode range of -0.1V to 36V. The amplifier offers a gain of 200 mV/A for the INA250A1 variant, with a maximum gain error of 0.3%. The input offset voltage has a maximum of 100,000 µV, and the gain error drift is rated at 45 ppm/°C. The bandwidth can reach up to 50 kHz, and the quiescent current is a maximum of 0.3 mA.

The integrated shunt resistor has a value of 2 mΩ with a tolerance of 0.1%. It supports continuous current up to 15A from -40°C to 85°C. The temperature coefficient of the shunt resistor is 10 ppm/°C. The operating temperature range for the device is -40°C to 125°C.

Packaged in a 16-pin TSSOP (PW) with dimensions of 5 mm x 6.4 mm (32 mm²), the INA250A1PW is suitable for low- or high-side current monitoring applications. Its bidirectional capability and integrated shunt resistor simplify system design for accurate current sensing.
