Maxim Integrated MAX44284HAWT+T Precision Current-Sense Amplifier

The MAX44284HAWT+T from Maxim Integrated is a high-precision, low-drift current-sense amplifier that offers an ideal solution for applications requiring accurate current monitoring. This device is specifically designed to amplify the small differential voltage developed across a current-sensing resistor in the presence of high common-mode voltages.

Featuring a wide input common-mode voltage range from -0.1V to +36V, the MAX44284HAWT+T is versatile and can be used in both single-supply and dual-supply applications. This makes it well-suited for industrial, automotive, and consumer applications where precise current measurement is critical, such as battery management systems, power management, and overcurrent protection circuits.

One of the key advantages of the MAX44284HAWT+T is its low input offset voltage, which ensures high accuracy in current measurement without the need for calibration. The device also boasts a low input bias current, further improving accuracy and reducing power consumption. With a gain accuracy of ±0.1% (max) and a gain drift of just 5ppm/°C, the MAX44284HAWT+T provides stable performance over a wide temperature range, making it reliable for use in harsh environments.

The MAX44284HAWT+T comes in a compact, 6-pin wafer-level package (WLP) with a tiny footprint, making it an excellent choice for space-constrained applications. Its low 10µV (max) input offset voltage and 0.5µV/°C (max) offset drift ensure that the device maintains precision without the need for frequent recalibration.

Additionally, the MAX44284HAWT+T features a shutdown mode that reduces the supply current to a mere 1µA (typ), which is particularly beneficial for battery-powered devices where power efficiency is paramount. The device operates over a wide temperature range from -40°C to +125°C, ensuring reliable performance in a variety of operating conditions.

Overall, the MAX44284HAWT+T is an excellent choice for design engineers looking for a high-precision, low-power current-sense amplifier that can deliver consistent performance across a range of demanding applications.
