Overview

The INA241x is an ultra-precision, bidirectional current-sense amplifier that measures the voltage drop across a shunt resistor over a wide common-mode range of -5V to 110V, independent of the supply voltage. High-accuracy current measurement is achieved through a combination of low offset voltage (±10μV maximum), tight gain error (±0.01% maximum), and high DC common-mode rejection ratio (166dB typical). The INA241x is designed for high-voltage, bidirectional measurement in switching systems where large common-mode voltage transients appear at the device inputs. An enhanced PWM rejection circuit inside the INA241x minimizes output signal disturbance during input common-mode voltage transitions. The INA241x operates from a 2.7V to 20V single supply with a supply current of 2.5mA. The INA241x is available in five gain options: 10V/V, 20V/V, 50V/V, 100V/V, and 200V/V. Multiple gain options allow optimization between available shunt resistance values and wide output dynamic range requirements. The INA241x is rated for operation over the -40°C to 125°C temperature range.
