INA139NA/250 Description

Short technical summary and product information.

The Texas Instruments INA139NA/250 is a unipolar, high-side current shunt monitor designed for precise current measurement. It operates over a wide supply and common-mode voltage range of 2.7V to 40V, allowing flexibility in power supply connections.

 

Key electrical specifications include an input offset voltage of ±1000µV maximum, an input offset drift of ±1µV/°C typical, and an adjustable voltage gain. The device offers a bandwidth of 220kHz and a gain error of 2% maximum, with a gain error drift of ±100ppm/°C maximum. Its accuracy is rated at ±0.5%.

 

Packaged in a SOT-23-5 (SC-74A, SOT-753) surface-mount package, the INA139NA/250 is suitable for space-constrained applications. It operates within a temperature range of -40°C to 125°C.

 

This current monitor is ideal for applications requiring accurate measurement of current flowing through a shunt resistor, such as power management systems, battery monitoring, and motor control.
