MAX4080SASA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4080SASA+ is a high-side, unidirectional current-sense amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a wide input common-mode voltage range of 4.5V to 76V, independent of the supply voltage. The device provides a fixed gain of 60V/V and operates from a single supply with a quiescent current of 75µA. It offers ±0.1% full-scale accuracy at room temperature and includes a low input offset voltage of 100µV. The component is housed in an 8-pin SO package and supports operation across an automotive temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Supports high-voltage monitoring with an independent 4.5V to 76V common-mode input range
• Provides high measurement precision through a 60V/V fixed gain and low input offset voltage
• Enables efficient power management via a low 75µA supply current consumption
• Delivers rail-to-rail output capability for direct interfacing with analog-to-digital converters

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive battery monitoring for 12V, 24V, or 42V systems
• Telecom and backplane current measurement
• Power-management system load sensing
• General board-level current sensing

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'SASA+' against official manufacturer documentation to confirm the 60V/V gain configuration and SOIC-8 packaging. Ensure compatibility with the required operating temperature range and supply voltage specifications before integration. Cross-reference the part number with authorized distributors to validate authenticity and RoHS compliance status.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-side current monitoring is required in systems with voltages up to 76V. The 60V/V gain is suitable for applications requiring precise detection of small sense voltages. Consider the 75µA quiescent current for low-power designs. Verify that the maximum sense voltage aligns with the selected external shunt resistor value to prevent saturation.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4080/MAX4081 family of high-side current-sense amplifiers. While the MAX4081 variant supports bidirectional sensing, the MAX4080 is designed specifically for unidirectional applications. The series integrates internal gain-setting resistors to minimize board space and simplify design implementation.
