INA310x/INA310x-Q1 Current Sense Amplifier

Texas Instruments INA310x/INA310x-Q1 Current Sense Amplifier is an ultra-precise current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range. This range is from –4V to 110V, independent of supply voltage with an integrated comparator. The high precision current measurement accuracy is achieved through a combination of low offset voltage (20µV, max.), small gain error (0.15%, max.), and a high DC CMRR (160dB, typical). The INA310x/INA310x-Q1 has a high signal bandwidth of 1.3MHz designed for high voltage DC current measurements and high-speed applications like fast overcurrent protection.
