Product details
Overview
MAX4222EEE+ from Maxim Integrated is a quad-channel, precision, closed-loop, gain-of-+2 rail-to-rail output buffer IC designed for high-fidelity video and RF signal routing. It delivers 230MHz -3dB bandwidth, 600V/µs slew rate, ±120mA output drive, 0.03% differential gain error, and operates from a single 3.15V to 11V supply - ideal for video multiplexing and analog-to-digital converter interface applications.
For engineers reviewing the MAX4222EEE+ datasheet, MAX4222EEE+ pinout, MAX4222EEE+ application, or MAX4222EEE+ equivalent, this page provides verified technical context, package-specific pin functions, real-world application cards, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The MAX4222EEE+ implements voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response. Its internal 500Ω precision resistors fix closed-loop gain at +2V/V (noninverting) or -1V/V (inverting), eliminating external gain-setting components.
It features rail-to-rail output swing (within 60mV of rails into 2kΩ), input common-mode range extending 100mV beyond VEE, and low 10nV/√Hz input voltage noise. No enable/disable function is present - unlike MAX4215/MAX4219 - confirming its fixed-operation, quad-buffer role in stable signal distribution paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4219ESD+ | Triple-channel, includes enable/disable control per amplifier; same 230MHz BW and 600V/µs SR | Used where power-gating of individual buffers is required (e.g., dynamic video path selection) | Select MAX4219ESD+ only when channel-level shutdown is needed; MAX4222EEE+ offers higher channel count without enable logic |
| THS3201DGN | Single-channel, 1.8GHz BW, 6000V/µs SR, but higher 12.5mA quiescent current and no internal gain resistors | Applied in ultra-wideband RF signal chains requiring >1GHz bandwidth, not video fidelity | Choose THS3201DGN for RF/IF amplification above 500MHz; MAX4222EEE+ is optimized for DC–230MHz video with guaranteed differential error specs |
Compared with MAX4219ESD+ and THS3201DGN, the MAX4222EEE+ uniquely combines quad-channel integration, internal +2V/V gain setting, sub-0.04° phase error, and 22mA total supply current - making it the only drop-in solution for compact, low-power, broadcast-compliant video multiplexers.

FAQ
What is the operating temperature range for the MAX4222EEE+?
The MAX4222EEE+ is specified for operation from -40°C to +85°C ambient temperature. This industrial-grade range is validated across all electrical parameters in the datasheet, including bandwidth, output swing, and differential gain error - ensuring reliable performance in video equipment deployed in uncontrolled environments.
Does the MAX4222EEE+ include an enable/disable function?
No, the MAX4222EEE+ does not include an enable/disable feature. Unlike the MAX4215/MAX4219 variants, the MAX4222EEE+ is a fixed-operation quad buffer with no EN pin. Its quiescent current remains at 5.5mA per amplifier (22mA total) under all operating conditions - confirmed by the selector guide and pin configuration diagrams.
What package type is used for the MAX4222EEE+?
The MAX4222EEE+ uses a 16-pin QSOP package (5.3mm × 10.2mm body, 0.635mm lead pitch). This surface-mount package is explicitly listed in the Ordering Information table as "MAX4222EEE+" and matches the pinout shown in Figure 13 of the datasheet for the QSOP variant.
Can the MAX4222EEE+ be used in inverting gain configurations?
Yes, the MAX4222EEE+ supports inverting gain-of-−1V/V configuration using its internal 500Ω resistors. Per the Applications Information section, grounding the noninverting input and applying the signal to the inverting input achieves −1V/V gain - with proper 56Ω (50Ω systems) or 88Ω (75Ω systems) input termination to maintain impedance match and minimize reflections.
What is the maximum capacitive load the MAX4222EEE+ can drive without instability?
The MAX4222EEE+ is designed to drive up to 20pF of load capacitance without oscillation. Driving larger capacitive loads (e.g., long PCB traces or unterminated cables) requires an isolation resistor - typically 27Ω for 68pF loads - as shown in Figure 9 of the datasheet. Exceeding 20pF without compensation risks peaking and gain margin degradation.
