MAX4434EUK/V+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4434EUK/V+T is a single-channel, voltage-feedback operational amplifier from the MAX4434–MAX4437 family. It features a small-signal -3dB bandwidth of 150MHz and operates with a supply voltage range of +4.5V to +5.5V. The device draws 15mA quiescent current per amplifier and provides an open-loop gain of 115dB. It achieves 16-bit settling time in 35ns at unity gain (+1V/V) and delivers up to 65mA output drive current. Input voltage noise density is 2.2nV/√Hz, supporting high-fidelity signal processing.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'EUK' corresponds to the 5-pin SOT23 package configuration as specified in the manufacturer's selector guide. Confirm the '+T' designation indicates lead-free/RoHS-compliant packaging. Ensure the component matches the single-channel variant rather than the dual-channel version within the same product family.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this part when unity-gain stability is required for the application circuit. Note that alternative models in the series are compensated for closed-loop gains of +5 or greater; verify the specific gain requirements before choosing between the MAX4434 and MAX4435 variants. Consider the space-saving 5-pin SOT23 package if board real estate is limited.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4434–MAX4437 series of single-supply, high-speed operational amplifiers designed for low-noise and ultra-low distortion performance. The series includes single and dual channel options packaged in SOT23 and μMAX formats, targeting modern data acquisition systems requiring fast settling times and wide bandwidths.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4435EUK+T serves as a functional substitute within the same package but requires a minimum closed-loop gain of +5 for stability.
