Product details
Overview
The MAX4104EUK-T from Maxim Integrated is a unity-gain-stable, ultra-high-speed voltage-feedback op amp in a 5-pin SOT23 package, delivering 625MHz -3dB bandwidth, 400V/µs slew rate, and 2.1nV/√Hz input voltage noise density. It operates on ±3.5V to ±5.5V dual supplies, draws only 20mA quiescent current, and drives ±70mA into loads - making it ideal for video ADC preamplification and high-fidelity pulse amplification in space-constrained telecom systems.
For engineers reviewing the MAX4104EUK-T datasheet, MAX4104EUK-T pinout, MAX4104EUK-T application, or MAX4104EUK-T equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application use cases, and two rigorously cross-checked alternative parts with documented functional and application differences.
Technical Context
The MAX4104EUK-T is a fully compensated, unity-gain-stable voltage-feedback amplifier optimized for AVCL = +1 operation. Its architecture delivers 100MHz 0.1dB gain flatness and maintains low differential gain/phase error (0.01%/0.01°) under NTSC conditions with 150Ω load - critical for broadcast-quality video signal integrity.
It features rail-to-rail output swing capability (±3.7V into 100kΩ), high PSRR (>85dB at DC), and robust CMRR (>95dB), enabling stable performance in noisy mixed-signal environments. The device supports full-power bandwidth up to 115MHz (2Vp-p) and achieves -88dBc SFDR at 5MHz with 100Ω load - confirming suitability for high-dynamic-range analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 625MHz at AVCL = +1 - enables baseband video and RF IF signal amplification without gain peaking or instability. |
| Slew Rate | 400V/µs - ensures faithful reproduction of fast-edged pulses (e.g., ADC sampling clocks, ultrasound bursts) without slew-induced distortion. |
| Voltage Noise Density | 2.1nV/√Hz at 1MHz - preserves SNR in low-level signal chains such as sensor interfaces and precision ADC drivers. |
| Spurious-Free Dynamic Range | -88dBc at 5MHz, RL = 100Ω - guarantees minimal harmonic contamination in telecomm and instrumentation applications. |
| Output Current Drive | ±70mA - directly drives 75Ω coaxial cables or parallel termination networks without external buffers. |
| Input Offset Voltage | ±1mV max - minimizes DC error accumulation in multi-stage gain blocks and active filter topologies. |
| Supply Current | 20mA typical at ±5V - balances ultra-high speed with power efficiency in portable or thermally constrained designs. |
Pinout & Package
The MAX4104EUK-T is housed in a RoHS-compliant, lead-free 5-pin SOT23-5 package (JEDEC MO-178AA), with thermal pad exposed on underside for enhanced power dissipation in high-current operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VEE | Negative supply rail | Must be connected to stable negative voltage (–3.5V to –5.5V); substrate tied internally to VEE for optimal isolation. |
| 2: IN– | Inverting input | Primary feedback node; requires matched trace length and impedance control when used in high-frequency closed-loop configurations. |
| 3: IN+ | Noninverting input | High-impedance input (1.5MΩ common-mode, 6kΩ differential); sensitive to layout parasitics above 100MHz. |
| 4: OUT | Amplifier output | Capable of ±70mA drive; requires local 0.1µF + 1nF ceramic bypassing and short microstrip routing to preserve 625MHz bandwidth. |
| 5: VCC | Positive supply rail | Must be connected to stable positive voltage (+3.5V to +5.5V); decoupling capacitors must be placed within 2mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Guaranteed stable at AVCL = +1 without external compensation - eliminates need for gain-setting resistors in buffer configurations. |
| Low differential gain/phase error | 0.01% / 0.01° at NTSC, RL = 150Ω - preserves color fidelity and timing accuracy in SD/HD video line drivers. |
| High output current drive | ±70mA into resistive or reactive loads - supports direct driving of 75Ω coax, ADC input capacitance (≥10pF), and active filter stages. |
| Wide output voltage swing | ±3.7V into 100kΩ - maximizes dynamic range in ±5V systems without clipping near supply rails. |
| Low input offset drift | ±0.5µV/°C typical - reduces temperature-dependent DC error accumulation across industrial operating range (–40°C to +85°C). |
Applications
| Video ADC Preamp | Pulse/RF Telecom Applications |
|---|---|

Use Value: Delivers 25ns settling to 0.1% with 400V/µs slew rate - critical for maintaining pulse fidelity and timing resolution in 1Gbps+ data links. |
| Video Buffers and Cable Drivers | Ultrasound Imaging Front-End |
Use Scenario: Driving long coaxial cables (e.g., 75Ω, up to 100m) in CCTV, medical imaging, or test equipment video distribution. IC Role / Device Role / Timing Role: Active line driver with back-termination support and high output current to overcome cable loss and reflections.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4304EUK-T | Compensated for AVCL ≥ +2V/V; 740MHz bandwidth, 1000V/µs slew rate - higher gain-bandwidth product but unstable at unity gain. | Requires minimum gain of 2×; unsuitable for unity-gain buffer roles where MAX4104EUK-T excels. | Select MAX4304EUK-T only when fixed-gain ≥2 amplification is needed and board layout allows tighter feedback loop control. |
| ADA4817-1ARMZ | Unity-gain stable; 1GHz bandwidth, 250V/µs slew rate, 4.3nV/√Hz noise - lower noise floor but significantly reduced slew rate and output drive (±35mA). | Better for ultra-low-noise, lower-current applications (e.g., photodiode preamps); insufficient drive for 75Ω cable or ADC input charging. | Choose ADA4817-1ARMZ when noise dominates over drive strength and bandwidth requirements exceed 625MHz but slew rate >400V/µs is not required. |
Compared with MAX4304EUK-T and ADA4817-1ARMZ, the MAX4104EUK-T uniquely balances unity-gain stability, 625MHz bandwidth, 400V/µs slew rate, and ±70mA output drive - making it the only option among the three capable of serving as a drop-in video line driver or ADC input buffer without redesigning gain topology or adding output buffering stages.

FAQ
What is the operating temperature range for the MAX4104EUK-T?
The MAX4104EUK-T is rated for continuous operation from –40°C to +85°C ambient temperature. This industrial-grade range is validated across all AC and DC specifications in the official datasheet, including bandwidth, slew rate, and SFDR performance - ensuring reliability in outdoor telecom enclosures and medical imaging equipment.
Is the MAX4104EUK-T unity-gain stable, and what does that mean for circuit design?
Yes, the MAX4104EUK-T is explicitly unity-gain stable per its datasheet and internal compensation. This means it can be configured as a voltage follower (AVCL = +1) without external phase-compensation components, eliminating risk of oscillation in buffer applications - a key advantage over the MAX4304EUK-T, which requires minimum gain of +2V/V.
What is the maximum capacitive load the MAX4104EUK-T can drive without oscillation?
The MAX4104EUK-T can drive up to 10pF of capacitive load directly without oscillation. For larger loads (e.g., >15pF PCB trace capacitance or ADC input capacitance), an isolation resistor (RISO) of 10–20Ω must be placed in series with the output to maintain stability - as confirmed in Figure 5 and layout guidelines of the MAX4104 datasheet.
Does the MAX4104EUK-T support single-supply operation?
No, the MAX4104EUK-T is specified exclusively for dual-supply operation from ±3.5V to ±5.5V. It lacks rail-to-rail input common-mode range extending to either supply rail and is not characterized for single-supply use - attempting +5V/0V operation may result in undefined output behavior or damage due to absolute maximum rating violations.
How does the MAX4104EUK-T compare to the MAX4104ESA in terms of performance and packaging?
The MAX4104EUK-T and MAX4104ESA share identical electrical specifications, temperature range (–40°C to +85°C), and functionality. The only difference is packaging: MAX4104EUK-T uses a 5-pin SOT23-5 (surface-mount, space-saving), while MAX4104ESA uses an 8-pin SO package. Both are pin-compatible within their respective footprints and require identical biasing and bypassing.
