Product details
Overview
MAX4354ESD 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. It operates from a single +2.7V to +5.25V supply and is used in baseband signal conditioning for portable communications and keyless entry systems.
For engineers reviewing the MAX4354ESD datasheet, MAX4354ESD pinout, MAX4354ESD application, or MAX4354ESD equivalent, this page provides verified electrical specifications, SO-14 package layout, real-world use cases in low-voltage RF front-ends, and validated alternative op-amps with documented gain-bandwidth trade-offs.
Technical Context
The MAX4354ESD 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 maintaining rail-to-rail output swing within 350mV of each rail under 1kΩ load.
Designed for single-supply systems, it features ground-sensing input (common-mode range extends to VEE – 0.1V) and delivers 22mA sink/source output current. The 14-pin SO package supports four independent amplifiers with shared power rails and isolated signal paths to minimize crosstalk (–74dB at 1MHz).

| Slew Rate | 240V/µs - enables clean 2Vpp output steps with ≤8ns rise/fall time into 1kΩ |
| Supply Current (per amp) | 620µA - allows four-channel operation at <2.5mA total, ideal for battery-powered receivers |
| Input Common-Mode Range | VEE – 0.1V to VCC – 1.5V - accepts ground-referenced inputs in single-supply configurations |
| Rail-to-Rail Output Swing | Within 350mV of VEE and 180mV of VCC at 1kΩ - maximizes dynamic range in 3.3V systems |
| THD @ 1MHz | –68dB - preserves signal fidelity in ADC driver and active filter applications |
| Crosstalk (1MHz) | –74dB - ensures channel isolation in multi-channel sensor interfaces and I/Q demodulators |

| 3 (IND+) | Amplifier D noninverting input | Accepts differential or single-ended input; input bias current ≤3µA |
| 4 (VEE) | Negative power supply | Ground reference for all four amplifiers; must be connected to system GND |
| 5 (VCC) | Positive power supply | +2.7V to +5.25V single supply; bypass with 0.1µF ceramic capacitor near pin |
| 6 (INA+) | Amplifier A noninverting input | Primary input for channel A; input capacitance = 2pF limits stray feedback pole formation |
| 7 (INA–) | Amplifier A inverting input | Feedback node for A channel; requires low-inductance PCB routing to avoid oscillation |
| 8 (OUTA) | Amplifier A output | High-current output (±22mA) suitable for driving 50Ω transmission lines via series resistor |
| 9 (INB–) | Amplifier B inverting input | Shared layout symmetry with INA– and INC– ensures consistent channel matching |

| 11 (OUTB) | Amplifier B output | Independent output; no internal connection to OUTA/OUTC/OUTD |
| 12 (INC+) | Amplifier C noninverting input | Third channel input; same ESD protection and CMRR (60–100dB) as other inputs |
| 13 (INC–) | Amplifier C inverting input | Supports unity-gain stable configuration only when used with external compensation |
| 14 (OUTC) | Amplifier C output | Final channel output; thermal coupling with adjacent pins minimized by SO package layout |

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 |
|---|---|---|---|
| MAX4454ESD | Unity-gain stable; 200MHz bandwidth but lower slew rate (95V/µs); same SO-14 package and pinout | Better for unity-gain buffers and wideband AC-coupled circuits; unsuitable for +5V/V gain stages requiring fast settling | Select MAX4454ESD when gain = 1 and bandwidth >100MHz is required; MAX4354ESD preferred for fixed +5V/V gain with faster transient response |
| AD8034ARZ | Single 80MHz op-amp (not quad); 15mA supply current per amp; SO-8 package; higher noise (6nV/√Hz) | Requires four separate ICs and more PCB area; better for high-precision DC-coupled apps due to lower VOS (1.5mV typ) | Choose AD8034ARZ only if single-channel performance or superior DC specs outweigh quad integration and power savings of MAX4354ESD |
Compared with MAX4454ESD, the MAX4354ESD trades bandwidth for higher slew rate and stability at +5V/V, making it superior for fixed-gain IF amplification; versus AD8034ARZ, it delivers four channels in one SO-14 package at <25% the total supply current.

FAQ
What is the minimum stable closed-loop gain for MAX4354ESD?
The MAX4354ESD is internally compensated for minimum closed-loop gain of +5V/V. Operating at gains below +5V/V may cause instability, peaking, or excessive ringing. For unity-gain applications, use the pin-compatible MAX4454ESD instead. This gain constraint is process- and layout-verified across temperature and voltage ranges per the datasheet AC Electrical Characteristics table.
Does MAX4354ESD support rail-to-rail input operation?
No - the MAX4354ESD features rail-to-rail *output* but not rail-to-rail *input*. Its input common-mode voltage range is specified from VEE – 0.1V to VCC – 1.5V. At VCC = 3.3V, this means inputs must stay between –0.1V and +1.8V. Ground-sensing capability allows true 0V input, but inputs cannot swing to VCC. This is confirmed in the DC Electrical Characteristics table under "Input Common-Mode Voltage Range".
What is the maximum capacitive load the MAX4354ESD can drive without external isolation?
The MAX4354ESD is characterized to drive up to 22pF directly without significant ringing or instability, as stated in the AC Electrical Characteristics table under "Capacitive Load Drive". Driving >22pF requires an isolation resistor (RISO) placed in series with the output - values are graphed in Figure 2 of the datasheet, e.g., 15Ω for 50pF load. This limit applies per amplifier channel independently.
How does the power supply rejection ratio (PSRR) of MAX4354ESD perform at 1MHz?
At 1MHz, the MAX4354ESD maintains a PSRR of 40dB (typical), as shown in the "POWER-SUPPLY REJECTION vs. FREQUENCY" plot (toc21). This means a 100mV ripple on VCC induces ~1mV error at the output. PSRR degrades above 100kHz due to internal compensation; for sensitive applications, local 0.1µF + 10µF bypassing at the VCC pin is mandatory per Layout guidelines.
Is the MAX4354ESD pinout compatible with other devices in the MAX445x/MAX435x family?
Yes - the MAX4354ESD shares identical pinout and footprint with MAX4454ESD, MAX4354EUD, and MAX4454EUD in their respective SO-14 and TSSOP-14 packages. Pin mapping (e.g., Pin 1 = OUTD, Pin 4 = VEE) is standardized across all quad variants per the "Pin Configurations" section (page 14) and "Pin Description" table (page 11). This enables drop-in replacement between gain-stable variants when board layout permits.
