Product details
Overview
MAX4354EUD+ from Maxim Integrated is a quad, high-speed, rail-to-rail output operational amplifier compensated for minimum closed-loop gain of +5V/V, delivering 80MHz -3dB bandwidth, 240V/µs slew rate, and 620µA supply current per amplifier while operating from +2.7V to +5.25V single supply - ideal for battery-powered baseband signal conditioning in keyless entry transceivers.
For engineers reviewing the MAX4354EUD+ datasheet, MAX4354EUD+ pinout, MAX4354EUD+ application, or MAX4354EUD+ equivalent, this page provides verified electrical specifications, TSSOP-14 package layout, real-world use cases in portable RF front-ends, and validated alternative op-amps with documented gain-bandwidth trade-offs.
Technical Context
The MAX4354EUD+ employs voltage-feedback architecture with internal compensation optimized for stable operation at AVCL ≥ +5V/V. Its bipolar process enables fast large-signal response (8ns rise/fall time) and low distortion (–74dBc SFDR at 1MHz), while rail-to-rail output swing (within 180mV of rails into 1kΩ) supports full dynamic range in 3V systems.
Input common-mode range extends from VEE – 0.1V to VCC – 1.5V, enabling ground-sensing capability without phase reversal. Output stage uses demand-driven biasing to maintain low open-loop impedance (<0.8Ω at 1MHz), ensuring consistent gain across varying capacitive loads up to 22pF when used with isolation resistors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW but 4.3mA supply current per amp; not rail-to-rail output | Requires dual supply for full swing; unsuitable for 3V-only systems | Select when ultra-wide bandwidth outweighs power budget constraints |
| ADA4891-4ARUZ | Unity-gain stable (225MHz BW), 1.2mA per amp, rail-to-rail I/O, same TSSOP-14 package | Lower power than LMH6629 but higher current than MAX4354EUD+; better DC precision | Choose for mixed-signal systems needing unity-gain stability and tighter offset specs |
Compared with LMH6629MA/NOPB and ADA4891-4ARUZ, the MAX4354EUD+ uniquely balances 80MHz bandwidth, 620µA quiescent current, and +5V/V minimum gain stability in a quad TSSOP - making it optimal for space-constrained, battery-operated RF baseband chains where power efficiency and predictable closed-loop behavior are prioritized over raw speed.

FAQ
What is the minimum stable closed-loop gain for the MAX4354EUD+?
The MAX4354EUD+ is internally compensated for stable operation at a minimum closed-loop gain of +5V/V. Attempting unity-gain or gains below +5V/V may cause peaking or oscillation without external compensation. This design choice enables higher bandwidth (80MHz) and slew rate (240V/µs) while maintaining robust phase margin in fixed-gain applications like IF amplifiers and active filters. Always verify stability with actual load conditions using the recommended 0.1µF VCC bypass capacitor.
Can the MAX4354EUD+ operate from a 3.3V supply?
Yes, the MAX4354EUD+ operates fully specified from +2.7V to +5.25V single supply, including standard 3.3V rails. At VCC = 3.3V, it delivers 620µA per amplifier quiescent current, 80MHz –3dB bandwidth, and rail-to-rail output swing within 180mV of both rails into 1kΩ. Input common-mode range extends from ground to 1.8V, supporting direct connection to 3.3V logic and sensors. Performance remains consistent across the entire voltage range without derating.
What is the maximum capacitive load the MAX4354EUD+ can drive directly?
The MAX4354EUD+ is characterized to drive up to 22pF capacitive load directly while maintaining stability and specified AC performance. Driving larger loads (e.g., ADC input capacitance + PCB trace capacitance >22pF) requires an isolation resistor (RISO) between the amplifier output and the load - typically 10Ω to 30Ω depending on load value - to restore phase margin. Figure 2 in the datasheet provides RISO vs. CLOAD curves; for example, 100pF load requires ~22Ω RISO. Never omit RISO when driving >22pF.
Does the MAX4354EUD+ have rail-to-rail input capability?
No, the MAX4354EUD+ does not feature rail-to-rail input. Its input common-mode voltage range is specified from (VEE – 0.1V) to (VCC – 1.5V). With VEE = 0V and VCC = 3.3V, this means inputs must stay between 0V and 1.8V - excluding the top 1.5V of the supply. However, the "ground-sensing" lower bound (down to –0.1V) allows direct connection to grounded sensors or AC-coupled signals referenced to ground. For true rail-to-rail input, consider alternatives like the ADA4891-4.
How is channel-to-channel crosstalk specified for the MAX4354EUD+?
Channel-to-channel crosstalk for the MAX4354EUD+ is specified as –74dB at 1MHz (typical), measured with one amplifier driven at 100mVpp while others are monitored under identical load conditions. This low coupling results from die-level isolation and careful layout of the quad amplifier core. In practice, this enables independent signal paths for I/Q processing or multi-sensor conditioning without significant inter-channel interference - critical for maintaining SNR in simultaneous sampling applications.
