The MAX4080FAUA+T is a high-side current-sense amplifier integrated circuit (IC) manufactured by Maxim Integrated. It is specifically designed for applications that require accurate current monitoring in the range of 0 to 1A.
One of the key features of the MAX4080FAUA+T is its ability to measure high-side currents while maintaining a low voltage drop across the sensing resistor. This is achieved by utilizing a high-gain instrumentation amplifier architecture that allows for accurate measurement of small voltage differentials. The IC also features a built-in precision voltage reference that provides excellent performance and stability over a wide temperature range.
Another notable feature of the MAX4080FAUA+T is its wide input voltage range, which is suitable for applications operating at a voltage supply of 3V to 36V. This allows the IC to be used in a variety of systems and offers flexibility in design.
The device is designed to be robust and immune to electromagnetic interference (EMI) or other sources of electrical noise. It incorporates a patented input current-limiting circuit that enhances its durability and protects it from potential damage due to overcurrent conditions. Its overcurrent protection feature helps prevent any voltage spikes or current transients from affecting the overall performance and integrity of the IC.
Furthermore, the MAX4080FAUA+T offers rail-to-rail output swing, meaning it can measure the full range of input currents within its specified limits, even when the input is close to the supply voltage rails
