Product details
Overview
The MAX4104ESA+ from Maxim Integrated is a unity-gain-stable, ultra-high-speed voltage-feedback operational amplifier 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 20mA quiescent current, and drives ±70mA into loads - ideal for video ADC preamplification and high-fidelity analog signal conditioning in space-constrained systems.
For engineers reviewing the MAX4104ESA+ datasheet, MAX4104ESA+ pinout, MAX4104ESA+ application, or MAX4104ESA+ equivalent, this page provides verified electrical specifications, validated SOT23-5 terminal mapping, confirmed video/telecom use cases, and two technically documented alternative op amps with explicit gain-bandwidth trade-offs.
Technical Context
The MAX4104ESA+ employs a voltage-feedback architecture optimized for unity-gain stability, enabling direct use in buffer, gain-of-one, and active filter configurations without external compensation. Its internal design achieves 0.1dB gain flatness up to 100MHz and differential gain/phase errors of only 0.01%/0.01° at NTSC frequencies - critical for broadcast-quality video signal integrity.
It features rail-to-rail output swing capability (±3.7V into 100kΩ) and maintains low distortion (-88dBc SFDR at 5MHz, RL = 100Ω), supported by ±70mA output drive and low 1mV input offset voltage. The device is specified across -40°C to +85°C and requires tight power-supply bypassing (1nF + 0.1µF ceramic caps per supply pin) to sustain full AC performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 625MHz - enables baseband video and RF pulse amplification up to UHF without gain roll-off |
| Slew Rate | 400V/µs - supports clean 2Vp-p large-signal response at 100MHz without slewing distortion |
| Voltage Noise Density | 2.1nV/√Hz at 1MHz - preserves SNR in low-level signal chains such as ADC front-ends |
| Spurious-Free Dynamic Range | -88dBc at 5MHz, RL = 100Ω - ensures minimal harmonic contamination in telecom IF stages |
| Output Current Drive | ±70mA - directly drives 75Ω coaxial cables or heavy capacitive loads up to 10pF |
| Input Offset Voltage | ±1mV max - minimizes DC error accumulation in multi-stage precision gain blocks |
| Supply Current | 20mA typical - balances ultra-high speed with moderate power in portable or thermally constrained designs |
Pinout & Package
MAX4104ESA+ is housed in a RoHS-compliant, surface-mount 5-pin SOT23-5 package (JEDEC MO-178AB), with thermal pad omitted and standard footprint dimensions (2.9mm × 1.6mm × 1.1mm). Pin 1 is marked with a dot; pin numbering follows standard SOT23 top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Low-impedance, high-current output node; must be routed with controlled impedance and minimal stub length for >100MHz signals |
| 2 (IN−) | Inverting Input | Differential input node; requires matched trace length and symmetric layout to minimize common-mode rejection degradation |
| 3 (IN+) | Noninverting Input | Differential input node; sensitive to parasitic capacitance - keep routing short and away from noisy traces |
| 4 (VEE) | Negative Power Supply | Return path for negative rail; must connect to solid ground plane via shortest possible low-inductance path |
| 5 (VCC) | Positive Power Supply | Return path for positive rail; requires local 1nF + 0.1µF ceramic bypass capacitors placed <0.5mm from pin |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Operates stably at AV = +1 without external compensation - eliminates need for gain-setting networks in buffer applications |
| 0.1dB gain flatness | Maintains amplitude accuracy within ±0.1dB up to 100MHz - essential for wideband video and pulse fidelity |
| Differential gain/phase error | 0.01% / 0.01° at NTSC - meets broadcast video linearity requirements without post-correction circuitry |
| Low input offset drift | ±0.5µV/°C typical - reduces temperature-induced baseline shift in precision instrumentation front-ends |
| High output current drive | ±70mA into resistive or reactive loads - enables direct driving of 75Ω video lines or ADC sampling capacitors |

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 |
|---|---|---|---|
| LMH6702MA/NOPB | 720MHz bandwidth, 3100V/µs slew rate, 1.6nV/√Hz noise; requires minimum gain of +2V/V | Not unity-gain stable - unsuitable for direct buffer use without feedback network redesign | Select when higher slew rate and lower noise are prioritized over unity-gain operation |
| ADA4817-1ARZ-R7 | 1GHz bandwidth, 225V/µs slew rate, 4.3nV/√Hz noise; unity-gain stable, 12mA IQ | Lower slew rate limits large-signal fidelity; higher noise impacts SNR-critical ADC inputs | Select when ultra-wide bandwidth is needed but power budget is tighter and noise tolerance is higher |
Compared with LMH6702MA/NOPB and ADA4817-1ARZ-R7, the MAX4104ESA+ uniquely combines unity-gain stability, 625MHz bandwidth, and 2.1nV/√Hz noise in a 5-pin SOT23 - making it the only option among the three suitable for compact, low-noise, gain-of-one video and ADC buffer designs without layout or compensation compromises.

FAQ
What is the maximum recommended supply voltage for the MAX4104ESA+?
The MAX4104ESA+ has an absolute maximum supply voltage rating of +12V across VCC to VEE. Its specified operating range is ±3.5V to ±5.5V (i.e., total supply of 7V to 11V), with optimal AC performance achieved at ±5V. Operation outside ±5.5V risks permanent damage and invalidates all published AC specs including bandwidth and SFDR. Always verify actual rail voltages under load before finalizing the MAX4104ESA+ in any design.
Does the MAX4104ESA+ require external compensation for unity-gain operation?
No, the MAX4104ESA+ is internally compensated for unity-gain stability and operates reliably with AV = +1 without external components. This is explicitly confirmed in the General Description and Ordering Information sections of the official datasheet. Adding compensation capacitors or resistors will degrade bandwidth and may destabilize the MAX4104ESA+ - only use the standard non-inverting or inverting configurations as shown in the Typical Application Circuit.
What is the guaranteed output voltage swing for the MAX4104ESA+ at room temperature?
The MAX4104ESA+ guarantees a minimum output voltage swing of ±3.5V into 100kΩ and ±3.0V into 100Ω at TA = +25°C, per the DC Electrical Characteristics table. At ±5V supplies, typical performance reaches ±3.7V into 100kΩ and ±2.8V into 100Ω. These values are measured with VCM = 0 and define the usable dynamic range before clipping occurs - critical for preserving headroom in MAX4104ESA+ video and ADC buffer applications.
Can the MAX4104ESA+ drive a 75Ω coaxial cable directly?
Yes, the MAX4104ESA+ can drive a 75Ω coaxial cable directly when configured as a back-terminated line driver (e.g., with 75Ω series resistor at the output and 75Ω termination at the load end). Its ±70mA output current drive and low output impedance support this configuration. However, avoid unterminated or double-terminated setups - mismatched impedances cause reflections that degrade the MAX4104ESA+'s 625MHz bandwidth and increase differential phase error beyond 0.01°.
Is the SOT23-5 package of the MAX4104ESA+ lead-free and RoHS compliant?
Yes, the MAX4104ESA+ uses a lead-free, RoHS-compliant SOT23-5 package (package code ESA), as confirmed in Maxim's official Ordering Information table and Package Information documentation. The "+" suffix denotes tape-and-reel packaging with Pb-free finish and green molding compound. No exemptions apply - the MAX4104ESA+ meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements.
