INA293/INA293-Q1 Current Sense Amplifiers

Texas Instruments INA293/INA293-Q1 High-Precision Current Sense Amplifiers measure voltage drops across shunt resistors from -4V to 110V. The negative common-mode voltage allows for operation below ground, 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. The INA293/INA293-Q1 is also designed for high-speed applications (ex. Fast over-current protection) with high bandwidth of 1.3MHz and an 85dB AC CMRR (at 50kHz). The INA293-Q1 devices are AEC-Q100 qualified for automotive applications.
