Overview

The INA241x-Q1 is an ultra-precise, bidirectional current sense amplifier than can measure voltage drops across shunt resistors over a wide commonmode 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-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-Q1 ensures minimal signal disturbance at the output due to the common-mode voltage transitions at the input. The INA241x-Q1 operates from a single 2.7 V to 20 V supply, drawing 2.5 mA of supply current. The INA241x-Q1 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-Q1 is specified over operating temperature range of -40 ℃ to +125 ℃.
