Product details
Overview
MAX4217EUA+ from Maxim Integrated is a dual-channel, precision, closed-loop +2/−1 gain rail-to-rail output buffer IC operating from 3.15V to 11V single supply or ±1.575V to ±5.5V dual supplies. It delivers 230MHz −3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and 0.03%/0.04° differential gain/phase error-optimized for video line drivers and ADC interface circuits in battery-powered instrumentation.
For engineers reviewing the MAX4217EUA+ datasheet, MAX4217EUA+ pinout, MAX4217EUA+ application, or MAX4217EUA+ equivalent, key selection criteria include dual-channel rail-to-rail output swing, fixed internal 500Ω feedback resistors for gain stability, low 5.5mA quiescent current per amplifier, and µMAX-8 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4217EUA+ implements voltage-feedback architecture enhanced with current-feedback techniques to achieve high-speed performance while maintaining closed-loop precision. Its internal 500Ω resistors set fixed noninverting (+2V/V) or inverting (−1V/V) gain configurations without external components.
Each channel features rail-to-rail output swing into 2kΩ loads (within 60mV of rails), input common-mode range extending 100mV beyond VEE, and low noise (10nV/√Hz voltage noise, 1.3pA/√Hz current noise). No enable/disable function is present-unlike MAX4215/MAX4219 variants-making it suitable for always-on signal conditioning paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.15V to 11V single supply or ±1.575V to ±5.5V dual supply - supports wide-input industrial and portable systems without level-shifting. |
| −3dB Bandwidth | 230MHz - enables full NTSC/PAL video bandwidth and high-fidelity RF signal buffering up to UHF. |
| Slew Rate | 600V/µs - ensures minimal distortion on fast transient signals such as video sync pulses and high-speed data edges. |
| Output Drive | ±120mA - drives 50Ω/75Ω coaxial cables directly or heavy capacitive loads with minimal external buffering. |
| Differential Gain/Phase Error | 0.03%/0.04° - meets broadcast-grade video fidelity requirements for professional analog video routing. |
| Quiescent Current | 5.5mA per amplifier - balances high-speed performance with low power in battery-operated test equipment. |
| Input Noise Density | 10nV/√Hz - preserves SNR in precision analog front-ends like CCD imaging and medical sensor interfaces. |
Pinout & Package
The MAX4217EUA+ is housed in an 8-pin µMAX package (pin-compatible with SO-8), measuring 3.0mm × 3.0mm × 0.8mm with exposed pad for thermal enhancement. Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise orientation from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting Input | 500Ω input impedance; used for −1V/V gain configuration or termination in 50Ω/75Ω video systems. |
| 2 (IN+) | Noninverting Input | High-impedance node; used for +2V/V gain when IN− is grounded; accepts input down to VEE − 100mV. |
| 3 (VEE) | Negative Supply / Ground | Reference for single-supply operation; supports ground-sensing input common-mode range extension. |
| 4 (OUTB) | Channel B Output | Rail-to-rail output capable of ±120mA sourcing/sinking; requires no external pull-up/down for DC-coupled video lines. |
| 5 (OUTA) | Channel A Output | Independent rail-to-rail output; matches OUTB in bandwidth, drive, and settling time for matched dual-path designs. |
| 6 (INA−) | Channel A Inverting Input | Dedicated inverting input for Channel A; electrically isolated from Channel B inputs to prevent crosstalk. |
| 7 (INA+) | Channel A Noninverting Input | Primary signal input for Channel A; shares same electrical characteristics as IN+ but assigned to first amplifier. |
| 8 (VCC) | Positive Supply | Accepts 3.15–11V; bypassing with 0.1µF ceramic capacitor near pin is mandatory for stable high-frequency operation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4217ESA+ | Same electrical specs; packaged in 8-pin SO (5.0mm × 4.0mm) instead of µMAX (3.0mm × 3.0mm). | Preferred for through-hole prototyping or legacy SO-8 footprints; less suitable for ultra-dense HD video PCBs. | Select MAX4217ESA+ when board real estate allows larger package or when SO-8 is required for mechanical compatibility. |
| THS3202D | Higher 1.8GHz bandwidth and 4000V/µs slew rate; no internal gain-setting resistors; requires external feedback network. | Better suited for RF IF amplification above 500MHz; lacks integrated video-optimized gain and differential error specs. | Choose THS3202D only when >1GHz bandwidth is mandatory and system-level calibration can compensate for missing internal precision resistors. |
Compared with MAX4217ESA+, the MAX4217EUA+ saves 54% board area with identical performance; versus THS3202D, it trades raw speed for plug-and-play video fidelity, eliminating external resistor matching and layout sensitivity in broadcast-grade designs.

FAQ
What is the operating temperature range for the MAX4217EUA+?
The MAX4217EUA+ is specified for operation from −40°C to +85°C. This industrial temperature range ensures reliable performance in battery-powered instruments, video surveillance enclosures, and factory-floor test equipment without derating. All DC and AC electrical characteristics-including 230MHz bandwidth and 0.03% differential gain error-are guaranteed across this full range.
Does the MAX4217EUA+ have an enable/disable pin?
No, the MAX4217EUA+ does not include an enable/disable function. Unlike the MAX4215/MAX4219 variants, it operates continuously whenever powered. Its quiescent supply current remains fixed at 5.5mA per amplifier-ideal for always-on video signal paths where shutdown sequencing adds complexity.
Can the MAX4217EUA+ be used in single-supply 3.3V applications?
Yes, the MAX4217EUA+ supports single-supply operation from 3.15V to 11V. At 3.3V, it maintains rail-to-rail output swing (within 60mV of rails into 2kΩ), 230MHz bandwidth, and 0.03% differential gain error-making it suitable for portable 3.3V video capture devices and low-voltage ADC front-ends.
What is the input common-mode voltage range of the MAX4217EUA+?
The MAX4217EUA+ input common-mode voltage range extends from (VEE − 100mV) to (VCC − 2.25V). In single-supply 5V operation with VEE = 0V, this means inputs can go as low as −100mV-enabling ground-referenced signal handling-and as high as +2.75V, supporting wide dynamic range in video and sensor interfaces.
How does the MAX4217EUA+ achieve its low differential gain and phase error?
The MAX4217EUA+ achieves 0.03%/0.04° differential gain/phase error through precision internal 500Ω feedback resistors, optimized voltage-feedback architecture with current-feedback enhancements, and matched transistor pairs in the output stage-all laser-trimmed during production. This eliminates resistor tolerance-induced errors and ensures consistent performance across temperature and supply voltage variations.
