MAX4493AUK+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4493AUK+T is a single-channel operational amplifier from the MAX4493 family, housed in a 5-pin SOT23 package. It operates on dual supplies ranging from ±2.25V to ±5.5V or a single supply of +4.5V to +11V. Key electrical specifications include a unity-gain bandwidth of 5MHz, quiescent current of 770µA per amplifier, and an open-loop gain of 110dB with a 100kΩ load. The device features rail-to-rail output swing, extending within 10mV of either rail under light loads, and supports input common-mode voltages from 200mV below the negative rail to 1.5V below the positive rail. It maintains stability with capacitive loads up to 300pF and exhibits low total harmonic distortion plus noise of 0.002% at 1kHz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output stage capable of swinging within millivolts of supply rails while maintaining high large-signal voltage gain.
• Wide input common-mode voltage range extends operation beyond the negative supply rail, enhancing flexibility in signal conditioning applications.
• Unity-gain stable design ensures reliable performance in feedback configurations without requiring external compensation components.
• Low quiescent current consumption enables efficient operation in battery-powered systems without sacrificing bandwidth.

• Battery-powered portable electronics
• DAC output buffering stages
• Industrial control system signal conditioning
• Voltage reference generation circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'UK' corresponds to the 5-pin SOT23 package configuration as listed in the official Maxim Integrated ordering information. Confirm that the '+T' designation indicates tape-and-reel packaging if reel handling is required for assembly. Ensure the component meets the automotive temperature range specification of -40°C to +125°C for intended environmental conditions. Cross-reference the lead-free/RoHS compliance status indicated by the '+' symbol against current regulatory requirements for the target market.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op amp with space-saving SOT23 packaging is required alongside rail-to-rail output capabilities. It is suitable for designs needing wide input common-mode range extending below the negative rail. Consider this part for applications demanding low power consumption with moderate bandwidth needs around 5MHz. Verify that the 770µA quiescent current aligns with system power budgets and that the 300pF capacitive load stability meets drive requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4493/MAX4494/MAX4495 family of general-purpose operational amplifiers manufactured by Maxim Integrated. While the MAX4493 is the single-channel variant, the family includes dual (MAX4494) and quad (MAX4495) versions sharing similar electrical characteristics. All variants are designed for dual or single supply operation and feature low power consumption with high open-loop gain. The MAX4493AUK+T specifically denotes the single-channel version in a 5-pin SOT23 package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include the MAX4493AXK+T (SC70 package) and MAX4493AXK/V+T (SC70 package). These parts share identical electrical specifications but differ in physical footprint. No other cross-family replacements are confirmed in the provided documentation.
