MAX4435EUK-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4435EUK-T is a single-channel, high-speed voltage-feedback operational amplifier designed for demanding signal processing applications. It operates from a +4.5V to +5.5V supply and delivers a small-signal bandwidth of 150MHz with a slew rate of 388V/µs. The device achieves 16-bit accurate settling in 23ns at a closed-loop gain of +5V/V. Key electrical characteristics include a low input voltage noise density of 2.2nV/√Hz, an open-loop gain of 115dB, and a high output drive capability of up to 65mA. It is housed in a compact 5-pin SOT-23 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the component is lead-free and RoHS-compliant as per manufacturer standards. Ensure the ordering part number matches the exact temperature range and package type required for your design specifications before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this model over unity-gain stable variants when circuit designs require a minimum closed-loop gain of +5V/V. The internal compensation ensures stability at these higher gains while maximizing bandwidth and slew rate performance. Verify that the application does not demand unity-gain operation, as this would require the MAX4434 variant instead.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4434–MAX4437 family of single-supply, ultra-low distortion operational amplifiers. While the MAX4434 is compensated for unity-gain stability, the MAX4435 variant is optimized for higher gains. Both share similar bandwidth and noise characteristics but differ in their stability compensation points.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4434 serves as a functional substitute if the application requires unity-gain stability rather than gains of +5V/V or greater. Other members of the MAX443x family may be considered based on channel count requirements, though pinout compatibility varies between single and dual configurations.
