Add To BomINA2128U General Description
The INA2128U is a precision, dual-channel, current-shunt monitor IC manufactured by Texas Instruments. It's designed for current sensing in power management applications. The device offers a high common-mode voltage range, making it suitable for monitoring voltages in systems with high common-mode voltages, such as motor control and inverter applications. It features a high-accuracy differential amplifier with a fixed gain of 100V/V, providing precise measurements of small differential voltages across a shunt resistor. The INA2128U operates over a wide temperature range, from -40°C to 125°C, ensuring reliable performance in harsh environments. It also includes built-in protection features like reverse polarity protection and overcurrent detection to safeguard against faults. With its small footprint and integrated functionality, the INA2128U simplifies current sensing in various industrial and automotive applications
