Product details
Overview
The MAX4200ESA-T from Maxim Integrated is a single-channel, ultra-high-speed, open-loop buffer optimized for driving high-speed ADC inputs and 50Ω/75Ω transmission lines. It delivers 660MHz -3dB bandwidth, 4200V/μs slew rate, ±90mA output current drive, and operates from ±5V supplies with only 2.2mA quiescent current per buffer. Its low 2.1nV/√Hz voltage-noise density and absence of internal termination resistors make it suitable for precision analog signal routing in IF/communications systems.
For engineers reviewing the MAX4200ESA-T datasheet, MAX4200ESA-T pinout, MAX4200ESA-T application, or MAX4200ESA-T equivalent, this page provides verified technical context, real-world design meaning for key specs, package-validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional and interface differences.
Technical Context
The MAX4200ESA-T uses a proprietary open-loop architecture that eliminates dominant-pole compensation, enabling near-constant 405ps group delay across its full frequency range. Unlike closed-loop amplifiers, it avoids phase-shift-induced instability with capacitive loads while maintaining stability up to 220pF without oscillation.
Its input presents 500kΩ || 2pF impedance, and its output resistance is 8Ω (typ), allowing direct drive into 150Ω loads with ±3.8V swing. Gain remains stable at 0.9–1.1V/V under 150Ω load due to local feedback around the Class-AB output stage, reducing sensitivity to load variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 660MHz - supports full-power signal delivery up to ~490MHz (FPBW) in high-speed data acquisition paths |
| Slew Rate | 4200V/μs - enables clean 2V-step response in ≤12ns (0.1% settling), critical for fast DAC/ADC interface timing |
| Output Current Drive | ±90mA - sustains ±3.8V swing into 150Ω loads, sufficient for driving unterminated coax or ADC input networks |
| Voltage-Noise Density | 2.1nV/√Hz - preserves SNR in front-end buffering of low-amplitude RF/IF signals before digitization |
| Supply Current | 2.2mA per buffer - enables low-power operation in multi-channel instrumentation without thermal derating |
| Input Offset Voltage | 1mV (min), 15mV (max) - ensures DC accuracy within ±0.5% gain error over input range in precision signal chains |
| Operating Temp Range | -40°C to +85°C - qualified for industrial-grade embedded communications and test equipment deployment |
Pinout & Package
MAX4200ESA-T is housed in an 8-pin SOIC package (package code S8-2), with exposed pad not connected. Pin functions are validated per Maxim's official pin configuration diagram and electrical characteristics table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N.C. | No internal connection; must be left unconnected or tied to ground per layout best practice |
| 2 | IN | Differential-input-capable single-ended buffer input; 500kΩ || 2pF impedance requires controlled-impedance trace routing |
| 3 | VEE | Negative supply rail (−5V); requires local 0.1μF ceramic bypass to ground, placed <1mm from pin |
| 4 | OUT | High-current buffer output; 8Ω output impedance enables direct drive into 150Ω loads without external series resistor |
| 5 | N.C. | No internal connection; must be left unconnected or tied to ground per layout best practice |
| 6 | N.C. | No internal connection; must be left unconnected or tied to ground per layout best practice |
| 7 | VCC | Positive supply rail (+5V); requires local 0.1μF ceramic bypass to ground, placed <1mm from pin |
| 8 | N.C. | No internal connection; must be left unconnected or tied to ground per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Open-loop architecture | Eliminates dominant-pole compensation, delivering flat group delay (405ps) across 100kHz–1GHz for phase-critical IF signal routing |
| No internal termination | Enables flexible system-level impedance matching-supports 150Ω, 100Ω, or custom back-termination without fixed 50Ω/75Ω loss |
| Capacitive-load tolerance | Stable operation up to 220pF without oscillation, simplifying PCB layout for ADC driver applications with long traces or connectors |
| Low-noise performance | 2.1nV/√Hz voltage noise + 0.8pA/√Hz current noise preserves dynamic range in wideband receiver front ends |
| High output current | ±90mA sourcing/sinking capability maintains signal integrity into reactive loads (e.g., ADC input capacitance + PCB trace) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-loop buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4201ESA-T | Includes integrated 50Ω output termination; 780MHz -3dB bandwidth; ±52mA output drive | Optimized for 50Ω coaxial cable drivers; lower output swing (±2.1V into 50Ω) vs. MAX4200ESA-T's ±3.8V into 150Ω | Select when driving 50Ω transmission lines directly-eliminates need for external series resistor but reduces voltage headroom |
| LMH6723MA/NOPB | Single 1.8GHz GBW VFA with 3100V/μs slew rate; closed-loop architecture; requires external compensation | Needs feedback network for gain setting; higher power (12.5mA); not inherently stable into capacitive loads without careful layout | Select when precise gain control (e.g., G = 2) is required and board space allows for feedback components and layout optimization |
Compared with MAX4201ESA-T, MAX4200ESA-T offers higher output voltage swing and no fixed termination-ideal for non-standard loads-but trades 120MHz bandwidth. Versus LMH6723MA/NOPB, MAX4200ESA-T delivers superior capacitive-load stability and lower quiescent current, at the cost of programmable gain flexibility.

Manufacturer
Maxim Integrated (now part of Analog Devices) designs high-performance analog and mixed-signal ICs for precision, high-speed, and power-efficient applications across industrial, communications, and computing markets.
The MAX4200–MAX4205 family was engineered specifically for ultra-wideband open-loop buffering in RF/IF signal chains where phase linearity, slew-limited transient response, and capacitive-load immunity are critical-distinct from general-purpose op-amps or current-feedback amplifiers.
FAQ
What is the maximum capacitive load the MAX4200ESA-T can drive without oscillation?
The MAX4200ESA-T remains stable with up to 220pF of capacitive load without oscillation, as confirmed in the "Output Capacitive Loading and Stability" section of the official datasheet. This stability arises from its open-loop architecture, which avoids the phase-shift feedback loops that cause instability in closed-loop amplifiers. For optimal bandwidth preservation, use an isolation resistor (e.g., 10Ω) when driving >47pF loads.
Does the MAX4200ESA-T have internal termination resistors?
No, the MAX4200ESA-T has no internal termination resistors. Per the Selector Guide and Detailed Description, only MAX4201/MAX4204 (50Ω) and MAX4202/MAX4205 (75Ω) include integrated output terminations. The MAX4200ESA-T's lack of internal termination provides full flexibility for system-level impedance matching-enabling use with 100Ω, 150Ω, or custom back-terminated configurations without signal loss from fixed dividers.
What is the typical output voltage swing of the MAX4200ESA-T into a 150Ω load?
The MAX4200ESA-T delivers a typical output voltage swing of ±3.8V into a 150Ω load at ±5V supplies, as specified in the DC Electrical Characteristics table under "Output-Voltage Swing." This exceeds the ±3.3V minimum and enables full-scale drive into high-impedance ADC inputs or passive filter networks without clipping, provided the load remains resistive or lightly capacitive (<20pF).
Can the MAX4200ESA-T operate from a single +10V supply?
No, the MAX4200ESA-T requires dual ±4V to ±5.5V supplies, as stated in the Absolute Maximum Ratings and Operating Supply Voltage specification. It is not designed for single-supply operation. Attempting to bias inputs or outputs at mid-rail on a +10V rail violates the "Voltage on Any Pin to GND" limit of (VEE − 0.3V) to (VCC + 0.3V), risking latch-up or permanent damage. Use ±5V rails with proper bypassing.
How does the MAX4200ESA-T achieve constant group delay?
The MAX4200ESA-T achieves a nearly constant 405ps group delay by using a proprietary open-loop architecture that omits the dominant-pole compensation found in voltage-feedback amplifiers. Without internal phase-shifting feedback networks, the device avoids frequency-dependent delay variation-making it suitable for phase-sensitive IF/RF signal routing where inter-stage skew must remain predictable across 100kHz–1GHz.
