Description
The INA139NA/250 is a precision voltage measurement amplifier designed by Texas Instruments. This Amplifier is an important component for high-side current sensing applications that require accurate measurement of voltages. The device can operate with a single power supply of up to 36 volts and has a maximum input voltage range of 40 volts. The output of the amplifier is rail-to-rail and can maintain the input voltage range even when it is biased to the highest value. The INA139NA/250 also has a high common-mode rejection ratio of 120dB, meaning that it can accurately measure small differences in voltage between two points while blocking out any common mode voltage or interference. This makes it suitable for use in many industrial and automotive applications.
The device is built with a precision operational amplifier that offers a high input impedance of 10^12 ohms to minimize the effect of the measurement circuit on the results. Additionally, the amplifier has a low input offset drift and offset voltage, improves the accuracy of the amplifier over a wide range of operating temperatures. INA139NA/250 also features a wide bandwidth of 100kHz and is designed to be low noise for optimum performance. Furthermore, the device is offered in a compact SOP-8 package with thermal protection and short circuit protection circuitry for added safety and reliability. The INA139NA/250 has been an industry-standard amplifier solution for voltage measurement for many years and has been a go-to product for precise measurements in many applications
