Product Description
Maxim Integrated MAX44284FAUT+T is a precision voltage current sensing amplifier optimized for single supply operation between 1.7V and 5.5V. Packaged in a compact 6-pin SOT-23 format, it features ultra-low quiescent current of 41.5μA and a wide input common-mode voltage range from -0.1V to +36V. The device offers four fixed gain options to simplify design and supports operation in extreme temperature conditions from -40°C to +125°C, making it suitable for automotive and industrial environments.
The amplifier's high common-mode rejection ratio of 91.3dB and low offset voltage (as low as 2μV) deliver highly accurate current measurements. Its low input bias current and extremely low input offset temperature coefficient support stable and precise sensing under varying conditions.
This amplifier is designed for a broad range of applications including current sensing in DC-DC converters, power management in portable battery-powered systems, medical pulse oximeters, infusion pumps, notebooks, smartphones, and tablets.
Operates from a single 1.7V to 5.5V power supply. Surface mount 6-pin SOT-23 package ensures compact PCB footprint. Suitable for use with small current-sense resistors to maximize power supply efficiency. Designed to meet the rigorous temperature requirements of automotive applications.
Extends battery life in portable systems via low supply current. Voltage output compatible with analog signal conditioning. Balanced gain and noise performance with 3kHz gain bandwidth product. Set contains one Maxim Integrated MAX44284FAUT+T current sensing amplifier in SOT-23 package.
These amplifiers are critical components in industrial, automotive, medical, and consumer electronic applications requiring precise current measurement and monitoring.
