MAX4482AUA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4482AUA-T is a dual-channel, low-cost operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.5V to +5.5V supply and draws only 50μA of quiescent current per amplifier. The device features rail-to-rail output voltage swing, unity-gain stability with capacitive loads up to 400pF, and a gain-bandwidth product of 140 kHz. It includes an input offset voltage of ±5.5mV (max) and operates across the -40°C to +125°C temperature range. The component is housed in an 8-pin μMAX package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'A' grade designation matches required offset voltage specifications. Ensure the 'U' package code corresponds to the 8-pin μMAX form factor for PCB layout compatibility. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and RoHS compliance status before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel solution is required alongside space-constrained designs utilizing the 8-pin μMAX package. Consider its 50μA quiescent current for battery-powered applications requiring extended operational life. Evaluate its 140 kHz gain-bandwidth product against system frequency requirements. Verify that the ±5.5mV maximum input offset voltage meets the precision needs of the target application circuitry.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4480–MAX4483 family of general-purpose op amps designed for harsh environments. While the MAX4480 offers a single channel and the MAX4483 provides four channels, the MAX4482 specifically delivers dual-channel functionality. Unlike the MAX4481, it does not include a shutdown mode, maintaining continuous operation across the specified industrial temperature range.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same series include the MAX4482AKA+T (SOT-23-8 package) and MAX4482ASA+ (SOIC-8 package). These alternatives share identical electrical characteristics but differ in physical package dimensions and pinout configurations.
