INA293B1QDBVRQ1 Integrated Circuit Chip 1.3MHz Ultra-Precise Current Sense Amplifier

Product Description Of INA293B1QDBVRQ1
INA293B1QDBVRQ1 is a ultra-precise current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from –4 V to 110 V. The negative common-mode voltage allows the device to operate below ground, thus accommodating precise measurement of recirculating currents in half-bridge applications. The combination of a low offset voltage, small gain error and high DC CMRR enables highly accurate current measurement. INA293B1QDBVRQ1 is not only designed for DC current measurement, but also for high-speed applications (ex. Fast over-current protection) with a high bandwidth of 1.3 MHz and an 85-dB AC CMRR (at 50 kHz).
