INA240A1PW General Description
The INA240A1PW, manufactured by Texas Instruments, is a state-of-the-art current sense amplifier designed for use in automotive and industrial settings. With a wide input voltage range of 2.7V to 36V, this device offers flexibility and compatibility with a variety of systems. Its fixed gain of 50V/V ensures precise current measurements with minimal sense voltage drop, and its low offset voltage and drift make it highly accurate over a wide temperature range, from -40°C to 125°C. Moreover, its high common-mode rejection ratio of 100dB ensures accurate current measurements in noisy environments. The compact TSSOP-16 package makes it suitable for space-constrained applications, without compromising on performance or functionality. Whether used in automotive or industrial environments, the INA240A1PW is a reliable and versatile choice for high-side, bidirectional current shunt monitoring
