INA293A4QDBVRQ1, Current Sense Amplifiers AEC-Q100, -4-V to 110-V, 1.3-MHz, ultra-precise current sense amplifier 5-SOT-23 -40 to 125
Semiconductors\Integrated Circuits - ICs\Amplifier ICs\Current Sense AmplifiersINA293/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 operation below ground, accommodating precise measurement of recirculating currents in half-bridge applications. Combining 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 a high bandwidth of 1.3MHz and an 85dB AC CMRR (at 50kHz). The Texas Instruments INA293-Q1 devices are AEC-Q100 qualified for automotive applications.
