Product details
Overview
The MAX4100ESA from Maxim Integrated is a unity-gain stable, low-power, high-speed voltage-feedback operational amplifier optimized for composite video, RGB, and RF cable driving. It delivers 500MHz unity-gain bandwidth, 250V/µs slew rate, ±3.1V output swing into 100Ω, and 0.06%/0.04° differential gain/phase error - enabling precision video signal distribution in portable broadcast equipment.
For engineers reviewing the MAX4100ESA datasheet, MAX4100ESA pinout, MAX4100ESA application, or MAX4100ESA equivalent, this page provides verified specifications, SO-8 package layout, video-system design context, and validated alternative op amps for back-terminated 75Ω line driving.
Technical Context
The MAX4100ESA employs a voltage-feedback architecture with internal compensation for unconditional unity-gain stability. Its open-loop gain exceeds 500MHz at +1 closed-loop gain, maintaining 65MHz 0.1dB gain flatness and <0.1% harmonic distortion up to 10MHz under 2Vp-p output into 100Ω.
Designed specifically for driving 75Ω back-terminated coaxial cables, it operates from ±5V supplies, draws only 5mA quiescent current, and achieves 18ns settling to 0.1% with 80mA output drive capability - supporting fast transient response in video buffer and ADC driver roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 500MHz - enables full-spectrum baseband video (up to ~50MHz) with minimal phase shift in unity-gain buffers |
| Slew Rate | 250V/µs - supports clean 1080p/60Hz RGB transitions without slewing-induced distortion |
| Output Swing | ±3.1V into 100Ω - delivers >2Vp-p signal headroom for 75Ω terminated lines with DC coupling |
| Differential Gain/Phase | 0.06%/0.04° - meets broadcast-grade NTSC/PAL fidelity requirements for color accuracy |
| Supply Current | 5mA - allows dual-channel operation in battery-powered ultrasound or portable instruments |
| Input Voltage Noise | 6nV/√Hz - preserves SNR in low-level analog front-end buffering before ADCs |
| Settling Time | 18ns to 0.1% - ensures accurate pixel sampling in high-speed imaging data acquisition |
Pinout & Package
MAX4100ESA is housed in an 8-pin narrow SOIC (SO-8) package measuring 3.9mm × 4.9mm × 1.75mm (max height), with standard 1.27mm lead pitch and gull-wing leads compatible with automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | No Connection | Unbonded die pads - must remain unconnected on PCB; no internal circuitry attached |
| 2 | Inverting Input | High-impedance node for feedback network connection; input capacitance = 2pF |
| 3 | Noninverting Input | High-impedance reference input; common-mode range extends to ±2.5V |
| 4 | Negative Supply (VEE) | Connect to −5V rail; supports rail-to-rail output swing when loaded ≥100Ω |
| 6 | Amplifier Output | Capable of sourcing/sinking 80mA; requires 24Ω series resistor in unity-gain buffer configuration |
| 7 | Positive Supply (VCC) | Connect to +5V rail; bypass with 1000pF + 0.1µF ceramic capacitors placed ≤2mm from pin |
Key Features

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 12mA supply current; requires AVCL ≥5 for stability | Not unity-gain stable; unsuitable for direct replacement in video buffer circuits | Select only for higher-gain, higher-power applications where bandwidth >1GHz is mandatory |
| ADA4817-1ARMZ | 1GHz GBW, 1.3mA supply current, FET inputs; unity-gain stable with 2.5pF input capacitance | Lower input bias current (2pA) but higher voltage noise (4nV/√Hz); optimized for high-Z sensor interfaces | Prefer for ultra-low IB applications like photodiode transimpedance, not 75Ω video line driving |
Compared with LMH6629MA/NOPB and ADA4817-1ARMZ, the MAX4100ESA uniquely balances 500MHz bandwidth, unity-gain stability, 5mA power, and 75Ω drive capability - making it the only drop-in solution for legacy video distribution designs requiring proven NTSC/PAL compliance.

FAQ
What is the maximum capacitive load the MAX4100ESA can drive without oscillation?
The MAX4100ESA can directly drive up to 5pF capacitive load with stable unity-gain operation. For larger loads, a series isolation resistor (e.g., 24Ω for 10pF, ≤50Ω for ≤100pF) between the output and load is required to suppress peaking and ensure stability - as confirmed in Figure 4b and Figure 5b of the MAX4100ESA datasheet.
Does the MAX4100ESA support single-supply operation?
No, the MAX4100ESA is specified only for dual-supply operation from ±4.5V to ±5.5V. Its input common-mode range is centered at ground (±2.5V), and output swing is asymmetric below VEE or above VCC - making it incompatible with true single-supply configurations without level-shifting circuitry.
What is the recommended power-supply bypassing scheme for the MAX4100ESA?
Per the MAX4100ESA datasheet, use a 1000pF ceramic capacitor between each supply pin (VCC and VEE) and ground, placed within 2mm of the package. Add a parallel 0.1µF ceramic capacitor at each supply pin, and locate a 10µF low-ESR tantalum capacitor at the board's power entry point - with short, direct traces from the tantalum to VCC/VEE pins.
Is the MAX4100ESA pin-compatible with the MAX4101ESA?
Yes, the MAX4100ESA and MAX4101ESA share identical 8-pin SOIC pinouts and package dimensions. However, they differ in internal compensation: MAX4100ESA is unity-gain stable, while MAX4101ESA requires AVCL ≥2V/V - so swapping them requires verifying closed-loop gain topology and stability margins.
What video standards does the MAX4100ESA meet for differential gain and phase performance?
The MAX4100ESA achieves 0.06% differential gain and 0.04° differential phase error at 3.58MHz, satisfying EIA-770.1 (NTSC) and SMPTE RP-168 (PAL/SECAM) broadcast video fidelity requirements - as measured under standard test conditions with 75Ω back-terminated load and ±5V supplies.
