Instrumentation, Op Amps, Buffer Amps datasheet and documents for MAX4070AUA+T

MAX4070AUA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4070AUA+T is a bidirectional, high-side current-sense amplifier featuring an internal 2.5V reference. It operates from a single supply voltage ranging from 3.6V to 24V and supports a common-mode input range of 1.35V to 24V independent of the supply voltage. The device offers selectable gains of 50V/V or 100V/V via a Gain Select pin. It consumes 100µA during normal operation, reducing to 10µA in shutdown mode. The output voltage indicates charge/discharge polarity relative to the 2.5V reference.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Bidirectional high-side current sensing with continuous polarity indication
Internal precision 2.5V reference for simplified system design
Wide common-mode voltage range independent of supply voltage
Low power consumption with dedicated shutdown control

Instrumentation, Op Amps, Buffer Amps Applications

Notebook battery fuel gauging
Smart-battery pack monitoring
Cell-phone battery-current monitoring
Motor control systems
Power-management systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'AUA+' corresponds to the 8-pin µMAX package and automotive temperature rating (-40°C to +125°C). Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering code matches the exact functional requirements regarding the fixed 2.5V reference and gain selection capabilities before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed 2.5V reference is required for bidirectional current monitoring. It is suitable for applications where the supply voltage ranges from 3.6V to 24V. Consider the 8-pin µMAX package for space-constrained designs. Verify that the 100µA supply current meets system power budgets and that the 1.35V to 24V common-mode range covers the expected sense resistor voltages.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4069–MAX4072 family of low-cost, bidirectional, high-side current-sense amplifiers. Unlike the adjustable MAX4069 or external-reference MAX4072, the MAX4070 integrates a fixed 2.5V reference. It shares the same core topology and performance characteristics as other members of the series, differing primarily in reference configuration and minimum operating voltage.
