The INA2181A1IDSQR is a dual channel, bi-directional current sense amplifier from Texas Instruments with 26V maximum input voltage, 350 kHz bandwidth, 10 WSON package, and -40 to 125 operating temperature range. It is designed to measure low level current in in-line current sensing applications with a voltage drop across a shunt resistor. The two channels offer independent, two pin, differential input, and wide-input common mode range. It features high common mode rejection ratio, high signal-to-noise ratio, and matched, differential gain and phase. It also offers rail-to-rail input and output swings, low supply current, and low offset voltage for exceptional precision. The INA2181A1IDSQR is an ideal choice for high resolution current measurement and data acquisition systems.
