Product details
Overview
MAX4100ESA+ from Maxim Integrated is a unity-gain stable, low-power, high-speed voltage-feedback operational amplifier optimized for driving 75Ω back-terminated video and RF cables. It delivers 500MHz unity-gain bandwidth, 250V/µs slew rate, ±3.5V output swing, 80mA output drive, and 0.06%/0.04° differential gain/phase - enabling precision composite video distribution in portable instruments and broadcast systems.
For engineers reviewing the MAX4100ESA+ datasheet, MAX4100ESA+ pinout, MAX4100ESA+ application, or MAX4100ESA+ equivalent, key selection criteria include unity-gain stability, 5mA quiescent supply current, 65MHz 0.1dB gain flatness, differential distortion performance at 3.58MHz, and SO-8 package compatibility with high-frequency layout requirements.
Technical Context
The MAX4100ESA+ employs a voltage-feedback architecture with internal compensation for unconditional unity-gain stability. Its open-loop gain exceeds 500MHz with phase margin maintained above 60° across temperature and load conditions.
It operates from dual ±5V supplies (±6V absolute max), supports rail-to-rail input common-mode range (±2.5V), and drives 30Ω loads to ±2.0V while maintaining <0.1% settling in 18ns - critical for fast-pulse video buffering and ADC front-end applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 500MHz - enables full-spectrum baseband video signal amplification without peaking or instability at AVCL = +1. |
| Slew Rate | 250V/µs - supports clean 1080p/60Hz video edge transitions and fast-settling pulse responses. |
| Output Voltage Swing | ±3.5V (RL = ∞) - provides headroom for ±2.0V video signals into 75Ω loads with minimal clipping. |
| Supply Current | 5mA (typ) - allows battery-powered portable instrumentation with thermal budget under 471mW in SO-8. |
| Differential Gain/Phase | 0.06%/0.04° @ 3.58MHz - meets broadcast-grade NTSC/PAL color fidelity requirements. |
| Input Voltage Noise | 6nV/√Hz - preserves SNR in low-level analog signal conditioning before ADCs. |
| Settling Time | 18ns to 0.1% - ensures accurate sampling of fast video sync pulses and transient events. |
Pinout & Package
MAX4100ESA+ is housed in an 8-pin narrow SO (Small Outline) package per JEDEC MS-012, with 1.27mm pitch, 4.0mm × 5.0mm body, and exposed pad not present. Pin 1 is marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | No Connection | Internally unconnected; must remain floating - no tie to ground or supply. |
| 2 | Inverting Input | High-impedance node for feedback network; sensitive to parasitic capacitance - requires short trace routing. |
| 3 | Noninverting Input | High-impedance input for signal source; matched impedance critical in video line drivers. |
| 4 | VEE | Negative power supply pin (–5V); requires local 1000pF + 0.1µF ceramic bypass to ground plane. |
| 6 | OUT | Class-AB output stage capable of ±3.5V swing into high-Z and 30Ω loads; drives 75Ω coax directly. |
| 7 | VCC | Positive power supply pin (+5V); requires identical bypassing as VEE for PSR >55dB. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Guaranteed across –40°C to +85°C without external compensation - eliminates need for gain-setting resistors in buffer mode. |
| 65MHz 0.1dB gain flatness | Maintains amplitude consistency across SD/HD video baseband (0–6MHz) and RF modulation bands up to 65MHz. |
| 250V/µs slew rate | Prevents slew-induced distortion on fast video edges and digital clock harmonics up to 100MHz. |
| 80mA output drive | Directly drives two 75Ω back-terminated lines simultaneously without external buffers. |
| 0.06%/0.04° DG/DP | Meets EIA-770.1 specification for professional video equipment - preserves color saturation and hue accuracy. |
Applications
| Video Cable Driver | Ultrasound Imaging Front-End |

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 |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW but requires ≥5V/V closed-loop gain; not unity-gain stable. | Requires minimum gain of 5V/V - unsuitable for direct replacement in unity-gain video buffers. | Select only when fixed-gain ≥5 configuration is acceptable and board layout supports higher supply current (12.5mA). |
| ADA4817-1ARMZ | 1GHz GBW, 250V/µs slew, but 10.5mA supply current and different SO-8 pinout (IN+/IN− swapped). | Not pin-compatible; requires PCB redesign due to reversed input pins and higher thermal dissipation. | Consider only for new designs needing wider bandwidth and where layout can accommodate pin reassignment and thermal management. |
Compared with LMH6629MA/NOPB and ADA4817-1ARMZ, the MAX4100ESA+ uniquely combines guaranteed unity-gain stability, 5mA quiescent current, and broadcast-grade differential distortion - making it irreplaceable in portable video driver and low-power instrumentation roles without layout or gain constraint changes.

FAQ
What is the operating temperature range for the MAX4100ESA+?
The MAX4100ESA+ is specified for operation from –40°C to +85°C ambient temperature. All electrical characteristics - including 500MHz bandwidth, 250V/µs slew rate, and 0.06%/0.04° differential gain/phase - are guaranteed across this full industrial temperature range, with typical performance measured at +25°C.
Is the MAX4100ESA+ unity-gain stable, and how does it differ from the MAX4101ESA+?
Yes, the MAX4100ESA+ is internally compensated for unity-gain stability, allowing use as a buffer without external compensation. In contrast, the MAX4101ESA+ is optimized for closed-loop gains ≥2V/V and becomes unstable below AVCL = 2 - making the MAX4100ESA+ the only choice for direct unity-gain video line drivers and ADC input buffers.
What package type is used for the MAX4100ESA+?
The MAX4100ESA+ uses an 8-pin narrow SO (Small Outline) package compliant with JEDEC MS-012, measuring 4.0mm × 5.0mm with 1.27mm lead pitch. It is distinct from the µMAX package (discontinued for this part) and requires standard SO-8 footprint and reflow profile.
Can the MAX4100ESA+ drive 75Ω coaxial cable directly?
Yes, the MAX4100ESA+ is explicitly characterized to drive 75Ω back-terminated video cables, delivering ±3.1V minimum output swing into 75Ω loads. Its 80mA output current and low output resistance (<1Ω at 10MHz) ensure minimal signal reflection and distortion in broadcast and RGB video distribution.
What are the recommended power supply bypassing practices for the MAX4100ESA+?
For optimal high-frequency performance, place a 1000pF ceramic capacitor between each supply pin (VCC and VEE) and the ground plane, located within 2mm of the package. Add a parallel 0.1µF ceramic capacitor adjacent to each 1000pF unit, and use a 10µF low-ESR tantalum capacitor at the board's power entry point - all per Maxim's layout guidelines in the MAX4100ESA+ datasheet.
