Instrumentation, Op Amps, Buffer Amps datasheet and documents for MAX4080FAUA+

MAX4080FAUA+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4080FAUA+ is a high-side, unidirectional current-sense amplifier from Analog Devices/Maxim Integrated. It features a wide input common-mode voltage range of 4.5V to 76V, independent of the supply voltage. The device offers a fixed gain of 5V/V and operates on a single supply drawing 75µA. Key electrical parameters include a maximum input offset voltage of 100µV, a bandwidth of 250kHz, and a common-mode rejection ratio of 100dB. It is specified for an operating temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

High-side monitoring with a 4.5V to 76V common-mode input range
Fixed 5V/V gain configuration for simplified circuit design
Low quiescent current consumption of 75µA
Rail-to-rail output capability

Instrumentation, Op Amps, Buffer Amps Applications

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'U' corresponds to the µMAX package type during procurement. Confirm RoHS compliance status indicated by the '+' symbol. Ensure the unidirectional nature aligns with application requirements, as bidirectional variants exist within the same family. Cross-reference the datasheet revision date to confirm parameter accuracy.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed 5V/V gain is sufficient for the target full-scale sense voltage. The wide common-mode range supports high-voltage applications where the sense resistor is placed at the positive rail. Consider the 75µA supply current for low-power designs. Verify that the unidirectional output meets the polarity requirements of the load being monitored.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4080/MAX4081 family of 76V high-side current-sense amplifiers. The MAX4080 variant provides unidirectional sensing, while the MAX4081 supports bidirectional operation. The FAUA+ designation indicates a 5V/V gain version housed in an 8-pin µMAX package with lead-free/RoHS-compliant construction.
