Product details
Overview
MAX4217EUA from Maxim Integrated is a dual-channel, precision, closed-loop +2V/V or −1V/V rail-to-rail output buffer IC optimized for high-speed video and instrumentation signal conditioning. It delivers 230MHz −3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and operates from a single 3.15V–11V supply. It is used in video line drivers and analog-to-digital converter interface circuits where low differential gain/phase error (0.03%/0.04°) and wide bandwidth are critical.
For engineers reviewing the MAX4217EUA datasheet, MAX4217EUA pinout, MAX4217EUA application, or MAX4217EUA equivalent, key selection criteria include dual-channel configuration without enable, µMAX-8 package compatibility, rail-to-rail output swing under 2kΩ load, −40°C to +85°C temperature range, and verified performance in NTSC video routing with <−72dBc SFDR at 5MHz.
Technical Context
The MAX4217EUA implements voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and bandwidth while maintaining closed-loop stability. Its internal 500Ω precision resistors fix gain at +2V/V (noninverting) or −1V/V (inverting), eliminating external resistor matching requirements.
It features rail-to-rail output swing (within 60mV of rails into 2kΩ), input common-mode range extending 100mV beyond VEE, and low noise (10nV/√Hz voltage noise, 1.3pA/√Hz current noise). No enable pin is present-unlike MAX4215/MAX4219-making it suitable for always-on dual-buffer applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 230MHz −3dB small-signal bandwidth enables full HD video signal passband support without attenuation. |
| Slew Rate | 600V/µs ensures faithful reproduction of fast transient video edges and pulse signals without distortion. |
| Output Drive | ±120mA per channel drives 50Ω/75Ω coaxial lines directly or supports heavy capacitive loads with isolation resistor. |
| Supply Range | Single 3.15V–11V or dual ±1.575V–±5.5V operation simplifies power design in portable and industrial systems. |
| Differential Error | 0.03% gain error and 0.04° phase error meet broadcast-grade NTSC/PAL video fidelity requirements. |
| Quiescent Current | 5.5mA per amplifier (11mA total) balances speed and low-power operation in battery-sensitive instruments. |
| Input Noise | 10nV/√Hz voltage noise and 1.3pA/√Hz current noise preserve SNR in low-level analog front-ends. |
Pinout & Package
MAX4217EUA is housed in an 8-pin µMAX package (pin-compatible with SO-8), measuring 3.05mm × 3.05mm × 0.8mm, with exposed pad for thermal enhancement. The package is RoHS-compliant and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−A) | Inverting input of Channel A | Accepts signal for −1V/V gain configuration; 500Ω internal termination enables direct 50Ω/75Ω system interfacing. |
| 2 (IN+A) | Noninverting input of Channel A | Primary signal input for +2V/V gain; input common-mode extends to VEE − 100mV for ground-referenced inputs. |
| 3 (VEE) | Negative supply / ground | Reference for dual-supply operation or ground return in single-supply mode; substrate tied to this pin. |
| 4 (OUTA) | Output of Channel A | Rail-to-rail output capable of ±120mA sink/source; swings within 60mV of rails into 2kΩ load. |
| 5 (OUTB) | Output of Channel B | Independent rail-to-rail output identical to OUTA; supports dual-path signal routing or differential drive. |
| 6 (IN−B) | Inverting input of Channel B | Enables independent −1V/V gain on second channel; matched to IN−A for inter-channel consistency. |
| 7 (IN+B) | Noninverting input of Channel B | Independent +2V/V input path; allows simultaneous buffering of two signals with identical gain and bandwidth. |
| 8 (VCC) | Positive supply | Accepts 3.15V–11V single supply or positive rail of dual supply; requires local 0.1µF bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed closed-loop gain | Internal 500Ω resistors set precise +2V/V or −1V/V gain-no external components needed, eliminating resistor tolerance errors. |
| Rail-to-rail output | Drives loads to within 60mV of VCC or VEE into 2kΩ, maximizing dynamic range in low-voltage 3.3V systems. |
| Low distortion | −72dBc SFDR and −71dB THD at 5MHz ensure minimal harmonic corruption in ADC driver and CCD imaging applications. |
| High channel isolation | −95dB crosstalk at 10MHz prevents interference between channels in video multiplexing and routing systems. |
| Wide input voltage range | Operates with inputs as low as VEE − 100mV, enabling true ground-sensing in single-supply video signal chains. |

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 and pinout; packaged in 8-pin SO instead of µMAX-8. Slightly larger footprint (4.9mm × 6.0mm vs. 3.05mm × 3.05mm). | Better thermal dissipation in high-ambient environments; less space-constrained PCB layouts. | Select MAX4217ESA when board area permits and higher power dissipation margin is required. |
| THS3202D | TI dual current-feedback amplifier; 375MHz bandwidth, 3000V/µs slew rate, but no internal gain-setting resistors (requires external feedback network). | Higher speed for RF/IF applications; lacks integrated +2/−1 gain, increasing BOM count and layout sensitivity. | Select THS3202D only when >300MHz bandwidth is mandatory and design can accommodate external resistors and tighter layout controls. |
Compared with MAX4217ESA, the MAX4217EUA offers identical performance in a 50% smaller footprint-critical for portable video gear. Versus THS3202D, MAX4217EUA trades raw speed for integration, eliminating external resistors and simplifying layout while meeting broadcast video bandwidth and distortion requirements.

FAQ
What is the gain configuration of the MAX4217EUA?
The MAX4217EUA has internally trimmed 500Ω resistors that configure each channel for a precise closed-loop gain of +2V/V in noninverting mode (IN+ driven, IN− grounded) or −1V/V in inverting mode (IN− driven, IN+ grounded). No external resistors are required, ensuring consistent gain accuracy across temperature and process variation. This fixed-gain architecture is integral to the MAX4217EUA design and cannot be altered.
Does the MAX4217EUA have an enable/disable function?
No, the MAX4217EUA does not include an enable pin. Unlike the MAX4215 or MAX4219 variants, the MAX4217EUA is designed for continuous-operation dual-buffer applications. Its quiescent supply current is 5.5mA per amplifier (11mA total), with no shutdown mode. If low-power disable capability is required, MAX4215EUA or MAX4219ESD should be considered instead of MAX4217EUA.
What package type is used for the MAX4217EUA?
The MAX4217EUA uses the 8-pin µMAX package (also referred to as uMAX or uSOP), measuring 3.05mm × 3.05mm × 0.8mm with an exposed thermal pad. It is pin-compatible with standard SO-8 but occupies ~50% less board area. The µMAX package is RoHS-compliant and rated for operation from −40°C to +85°C, making it ideal for compact, high-density video and instrumentation PCBs.
Can the MAX4217EUA drive 75Ω video loads directly?
Yes, the MAX4217EUA can drive 75Ω video loads directly in both +2V/V and −1V/V configurations. When configured for −1V/V gain, the inverting input presents a 500Ω impedance-requiring a 88Ω series termination for optimal 75Ω system matching. Output swing remains rail-to-rail (within 60mV of rails into 2kΩ), and the ±120mA output current supports sustained 75Ω drive at 2VP-P levels without clipping, as verified in NTSC video testing.
What is the maximum capacitive load the MAX4217EUA can drive stably?
The MAX4217EUA is stable driving up to 20pF of capacitive load without external compensation. For loads exceeding 20pF-such as long PCB traces or unterminated cables-an isolation resistor (e.g., 27Ω) placed in series with the output restores stability and flattens frequency response, as documented in Figure 9 of the MAX4217EUA datasheet. Driving >68pF without isolation risks peaking or oscillation due to degraded phase margin.
