Description:

The INA241A5IDR is an ultra-precision bidirectional current detection amplifier that measures voltage drops on shunt resistors. This measurement is done in a wide common model range of -5V to 110V, independent of the supply voltage. High precision current measurement is achieved through a combination of small gain error (Max. ±0.01%), low offset voltage (Max. ±10µV), and high DC CMRR (typical value 166dB). The INA241x is suitable for high-voltage bidirectional measurement in switching systems that experience high common-mode transient voltages at the device input. Thanks to the common-mode voltage conversion at the input, an enhanced PWM suppression circuit inside the INA241x ensures minimal signal interference at the output.
