MAX4077ESA+ – General Purpose Amplifier 2 Circuit Rail-to-Rail 8-SOIC
The MAX4077ESA+ from Analog Devices Inc./Maxim Integrated is a high-side current-sense amplifier designed for precision current monitoring in a wide range of industrial, automotive, and power management applications. It features an ultra-low offset voltage (100µV max) and a fixed gain of 20V/V, enabling accurate measurement of small voltage drops across shunt resistors without requiring external calibration. The device operates from a single supply voltage of 2.7V to 28V, making it suitable for both low-voltage and high-voltage systems, including battery-powered equipment and industrial control circuits.
Engineered for high accuracy and low power consumption, the MAX4077ESA+ high-side current-sense amplifier delivers a low input bias current (10µA max) and a wide common-mode voltage range (0V to 28V), allowing it to monitor current in high-side configurations without ground reference limitations. Its rail-to-rail output swing ensures maximum dynamic range when interfacing with ADCs or microcontrollers. Additionally, the amplifier includes a built-in reference voltage (1.5V), simplifying system design by eliminating the need for an external reference in many applications.
The MAX4077ESA+ is housed in an 8-pin SOIC (ESA) package, providing a compact and robust solution for space-constrained designs. It is fully specified over the extended industrial temperature range (–40°C to +85°C), ensuring reliable operation in harsh environments. Common applications include battery management systems, motor control, power supplies, and overcurrent protection circuits.
Analog Devices Inc./Maxim Integrated ensures high reliability with robust ESD protection (2kV HBM) and lead-free, RoHS-compliant manufacturing. For engineers seeking a high-precision, high-side current-sense amplifier with wide voltage compatibility, the MAX4077ESA+ offers an ideal combination of performance, versatility, and ease of integration.
