Overview

The INA241x is an ultra-precise, bidirectional current sense amplifier than can measure voltage drops across shunt resistors over a wide common-mode range from -5 V to 110 V, independent of the supply voltage. The high-precision current measurement is achieved through a combination of low offset voltage (±10 μV, maximum), small gain error (±0.01%, maximum) and a high DC CMRR (typical 166 dB). The INA241x 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 ensures minimal signal disturbance at the output due to the common-mode voltage transitions at the input. The INA241x operates from a single 2.7 V to 20 V supply, drawing 2.5 mA of supply current. The INA241x is available in five gain options: 10 V/V, 20 V/V, 50 V/V, 100 V/V, and 200 V/V. Multiple gain options allow for optimization between available shunt resistor values and wide output dynamic range requirements. The INA241x is specified over operating temperature range of -40°C to +125°C.
