INA293 pdf资料下载The INA293 is a high-precision 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. The INA293 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). The INA293 operates from a single 2.7-V to 20-V supply, drawing 1.5 mA of supply current. The INA293 is available with five gain options: 20 V/V, 50 V/V, 100 V/V, 200 V/V, and 500 V/V. These gain options address wide dynamic range current-sensing applications.INA293A1IDBVR INA293A1IDBVT INA293A2IDBVR INA293A2IDBVT INA293A3IDBVR INA293A3IDBVT INA293A4IDBVR INA293A4IDBVT INA293A5IDBVR INA293A5IDBVT INA293B1IDBVR INA293B1IDBVT INA293B2IDBVR INA293B2IDBVT INA293B3IDBVR INA293B3IDBVT INA293B4IDBVR INA293B4IDBVT INA293B5IDBVR INA293B5IDBVT Datasheet pdf资料数据表下载
