MAX4435EUK+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4435EUK+T is a single-channel, high-speed operational amplifier from the MAX4434–MAX4437 family. It operates on a single +4.5V to +5.5V supply with a quiescent current of 15mA per amplifier. The device features a small-signal bandwidth of 150MHz and a slew rate of 388V/µs. It achieves 16-bit accurate settling in 23ns and provides an open-loop gain of 115dB. Input voltage noise density is 2.2nV/√Hz, supporting a spurious-free dynamic range of 97dB at 1MHz. The output can drive up to 65mA and swings within 200mV of the positive rail.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix matches the exact package type (SOT23) and temperature range (-40°C to +85°C). Confirm RoHS compliance status (+ denotes lead-free). Ensure the specific part number corresponds to the closed-loop gain stability requirements (+5 minimum), as unity-gain stable variants exist within the same family.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when driving high-speed ADCs requiring fast settling times and low noise. The MAX4435 is specifically designed for gains of +5 or higher; do not use for unity-gain configurations without external compensation. Consider the 15mA supply current and 65mA output drive against power dissipation limits in the SOT23 package.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4435EUK+T belongs to the MAX4434–MAX4437 series of single-supply, 150MHz op amps. This family bridges the gap between voltage feedback and current feedback amplifiers, offering wide bandwidth and high output drive in ultra-small packages. The 'E' indicates the industrial temperature range, while 'U' designates the SOT23 footprint.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4434EUK+T serves as a direct substitute if the application requires unity-gain stability instead of gain-of-five stability. Both share identical pinouts, bandwidth, and package dimensions.
