MAX4372TEBT+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4372TEBT+T is a low-cost, precision high-side current-sense amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 2.7V to 28V supply and consumes only 30µA of supply current. The device features a voltage output with a fixed gain of 20V/V, eliminating the need for external gain-setting resistors. It offers 0.18% full-scale accuracy and an input offset voltage of 0.3mV. The common-mode range extends from 0V to 28V, independent of the supply voltage. It is housed in a space-saving 3 x 2 UCSP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix '+T' corresponds to tape-and-reel packaging when sourcing this component. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated to ensure authenticity. Check for lead-free and RoHS compliance status indicated by the '+' symbol. Ensure the UCSP package type matches your PCB footprint requirements before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4372TEBT+T when a fixed 20V/V gain is appropriate for the target current range. Consider the UCSP package for applications requiring minimal board space compared to standard SOT23 options. Evaluate the 30µA supply current against system power budgets for battery-operated devices. Verify that the 0 to 28V common-mode range aligns with the maximum voltage present at the sense resistor terminals.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4372 family of micropower, high-side current-sense amplifiers. The family includes variants with different gains (50V/V and 100V/V) and packages (SOT23 and SO). The TEBT variant specifically denotes the 20V/V gain version in the ultra-small UCSP package. These devices are designed for portable electronics where space and power consumption are critical constraints.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consider the MAX4372FEUK+T or MAX4372HEUK+T if higher gain versions are required. For alternative packages, the MAX4372TESA+ offers an 8-pin SO option. Verify pin compatibility and gain specifications when substituting with other members of the MAX4372 series.
