INA241x/INA241x-Q1 Current Sense Amplifiers

Texas Instruments INA241x/INA241x-Q1 Current Sense Amplifiers are ultra-precise, bidirectional current sense amplifiers that can measure voltage drops across shunt resistors. This measurement is done over a wide common-mode range from -5V to 110V, independent of the supply voltage. The high-precision current measurement is achieved through a combination of small gain error (±0.01%, maximum), low offset voltage (±10µV, max), and a high DC CMRR (typical 166dB). The Texas Instruments INA241x/INA241x-Q1 is designed for high-voltage, bidirectional measurements in switching systems that see large common-mode voltage transients at the device’s inputs. The enhanced PWM rejection circuitry inside the INA241x/INA241x-Q1 ensures minimal signal disturbance at the output due to the common-mode voltage transitions at the input. The INA241x-Q1 devices are AEC-Q100 qualified for automotive applications.
