MAX44285TAUA+T Precision Current-Sense Amplifier from Maxim Integrated

The MAX44285TAUA+T is a high-accuracy, low-side current-sense amplifier designed by Maxim Integrated, a leader in analog and mixed-signal engineering. This precision amplifier is tailored for a wide array of applications, including power management, battery monitoring, and overcurrent protection in consumer, automotive, and industrial settings.

At the heart of the MAX44285TAUA+T is a patented auto-zeroing technique that ensures a low input offset voltage of just 10µV (max) and an input offset drift of 0.1µV/°C (max). These characteristics make it an excellent choice for applications demanding high precision over a wide temperature range. The device operates from a single 2.7V to 5.5V power supply, making it versatile for various system voltages.

This current-sense amplifier offers a wide input common-mode range from -0.1V to +36V, independent of the supply voltage, which allows for flexible circuit placement and the ability to handle high common-mode voltages. The MAX44285TAUA+T comes in a compact 8-pin µMAX package, which is ideal for space-constrained applications.

One of the key features of the MAX44285TAUA+T is its high accuracy, with a gain error of just 0.1% (max) and a gain error drift of 10ppm/°C (max). This precision is maintained across the full -40°C to +125°C operating temperature range, ensuring reliable performance in harsh environments.

Furthermore, the device boasts a 200kHz bandwidth and a low 250µA (typ) supply current, which is beneficial for power-sensitive applications. The MAX44285TAUA+T also features a 3µVp-p (typ) low input-referred noise over the 0.1Hz to 10Hz range, providing an excellent signal-to-noise ratio.

For engineers looking to integrate current measurement into their designs, the MAX44285TAUA+T offers a robust and precise solution. Its high accuracy, wide operating temperature range, and low power consumption make it a go-to component for current-sensing applications that demand the utmost in performance and reliability.

Maxim Integrated's commitment to quality and innovation ensures that the MAX44285TAUA+T current-sense amplifier stands out as a superior choice for designers who require a precise, reliable, and efficient solution for current measurement.
