Maxim Integrated MAX40080 Current-Sense Amplifier is a high-precision, fast-response, bi-directional current-sense amplifier. The MAX40080 has a digital output and a wide input common-mode range from -0.1V (ground sensing) to 36V. The device features an ultra-low 5µV input offset voltage and a very low 0.2% gain error. The low input offset voltage allows using a small sense resistor, saving power dissipation, but not compromising measurement accuracy.
