Product details
Overview
MAX4417EUA from Maxim Integrated is a dual, high-speed, rail-to-rail output operational amplifier optimized for closed-loop gains ≥ +5V/V, delivering 150MHz -3dB bandwidth and 470V/µs slew rate while consuming only 1.6mA per amplifier from a single +2.7V to +5.5V supply. It features ultra-low distortion (–79dBc SFDR at 5MHz, 0.01% THD), differential gain/phase error of 0.05%/0.35°, and operates across –40°C to +85°C in an 8-pin µMAX package - ideal for portable video line drivers and baseband signal conditioning.
For engineers reviewing the MAX4417EUA datasheet, MAX4417EUA pinout, MAX4417EUA application, or MAX4417EUA equivalent, this page delivers verified electrical specs, validated dual-amplifier pin configuration, real-world video and communications use cases, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The MAX4417EUA employs voltage-feedback architecture with internal compensation tailored for stable operation at closed-loop gains of +5V/V or higher. Its output stage uses demand-driven current biasing and internal feedback to maintain low open-loop output impedance (<0.5Ω at 1MHz), ensuring consistent gain under varying load conditions.
It supports rail-to-rail output swing (within 105mV of rails into 1kΩ) and ground-sensing input (common-mode range extends 0.1V below VEE to 1.5V below VCC), enabling full dynamic range utilization in single-supply +3V/+5V systems - critical for battery-powered instrumentation and video signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 150MHz at AV = +5V/V - enables accurate amplification of baseband video and IF signals up to ~75MHz fundamental frequency. |
| Slew Rate | 470V/µs - supports clean 2Vp-p step response with ≤5ns rise/fall time, minimizing transient distortion in fast-switching circuits. |
| Supply Current | 1.6mA per amplifier - allows dual-channel operation within 3.2mA total, suitable for power-constrained portable designs. |
| Input Common-Mode Range | VEE – 0.1V to VCC – 1.5V - permits direct interfacing with ground-referenced sensors and DAC outputs without level-shifting. |
| Differential Gain/Phase Error | 0.05% / 0.35° at NTSC - meets broadcast-grade video line driver requirements for minimal color fidelity loss. |
| Spurious-Free Dynamic Range | –79dBc at fC = 5MHz, VCC = +3V - ensures >13-bit effective resolution in ADC buffer applications. |
| Output Voltage Swing | Within 105mV of VCC/VEE into 1kΩ - delivers >4.6Vp-p output swing from +5V supply, maximizing SNR in single-supply systems. |
Pinout & Package
MAX4417EUA is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), thermally enhanced with exposed paddle, rated for –40°C to +85°C operation. Pinout is identical to industry-standard SO-8 but with smaller footprint and improved high-frequency performance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, drives 1kΩ load to within 105mV of supply rails. |
| 2 | INA– | Amplifier A inverting input - high-impedance node (16MΩ), sensitive to PCB parasitics above 10MHz. |
| 3 | INA+ | Amplifier A noninverting input - common-mode range extends 0.1V below ground, enabling true ground-referenced sensing. |
| 4 | VEE | Negative supply terminal - tied to ground in single-supply operation; requires local 0.1µF bypass to minimize PSRR degradation. |
| 5 | INB+ | Amplifier B noninverting input - electrically isolated from INA+; enables independent dual-channel signal paths. |
| 6 | INB– | Amplifier B inverting input - matched to INA– for <0.1dB gain matching and <0.1° phase matching up to 10MHz. |
| 7 | OUTB | Amplifier B output - fully independent of OUTA; supports crosstalk <–72dB at 10MHz between channels. |
| 8 | VCC | Positive supply terminal - accepts +2.7V to +5.5V; PSRR of 60–77dB ensures immunity to supply noise in mixed-signal environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW but consumes 12.5mA per amplifier; not rail-to-rail output (1.2V headroom); no ground-sensing input. | Better for wideband RF gain blocks where power is not constrained; unsuitable for single-supply video or low-voltage instrumentation. | Select when bandwidth >500MHz is required and supply >±5V is available; avoid for battery-powered or rail-to-rail output needs. |
| ADA4897-2ARZ | Lower 220MHz GBW but lower 1.4mA supply current; rail-to-rail output; ground-sensing input; –90dBc SFDR at 5MHz. | Superior distortion performance for audio and precision measurement; slightly reduced bandwidth limits video use to SD formats. | Prefer for low-distortion audio buffering or precision DC-coupled instrumentation; choose MAX4417EUA for HD video or faster baseband signals. |
Compared with LMH6629MA/NOPB and ADA4897-2ARZ, the MAX4417EUA uniquely balances 150MHz bandwidth, rail-to-rail operation, ground-sensing input, and ultra-low 1.6mA/quiescent current - making it the only dual op amp in its class qualified for portable HD video and battery-operated baseband signal chains.

FAQ
What is the minimum closed-loop gain supported by MAX4417EUA?
The MAX4417EUA is internally compensated for stable operation at closed-loop gains of +5V/V or greater. Using it at gains below +5V/V risks instability and peaking in frequency response. For unity-gain applications, the MAX4416EUA (unity-gain stable variant) is the appropriate selection. This design choice enables the MAX4417EUA to achieve higher bandwidth (150MHz vs. 400MHz for MAX4416EUA) and faster slew rate (470V/µs) within its specified gain range.
Does MAX4417EUA support true single-supply operation with input signals at ground potential?
Yes. The MAX4417EUA features a ground-sensing input with a common-mode voltage range extending to VEE – 0.1V (i.e., 0.1V below ground when VEE = 0V). This allows direct connection of ground-referenced sensors or DAC outputs without external level-shifting circuitry. The rail-to-rail output further enables full-swing signal delivery from a single +3V or +5V supply, making MAX4417EUA suitable for true single-supply portable instrumentation.
What is the maximum capacitive load the MAX4417EUA can drive without external isolation?
The MAX4417EUA is characterized for stable operation with up to 120pF of capacitive load at the output, provided the load is purely capacitive and no sustained oscillations occur. For reactive loads such as unterminated coaxial cables or ADC input capacitance combined with PCB trace inductance, Maxim recommends adding a small series isolation resistor (typically 20Ω–30Ω) between the amplifier output and the load to maintain phase margin and prevent ringing. This requirement is explicitly documented in the "Output Capacitive Loading and Stability" section of the MAX4417EUA datasheet.
How does the power-supply rejection ratio (PSRR) of MAX4417EUA perform across frequency?
The MAX4417EUA delivers 60–77dB PSRR over DC to 1MHz, degrading gradually to ~40dB at 100MHz. This performance is sufficient to suppress typical digital switching noise (e.g., from nearby microcontrollers or DC-DC converters) in mixed-signal portable systems. The PSRR curve is flat up to ~100kHz, then rolls off at –20dB/decade - a characteristic of its internal voltage-feedback architecture. For applications requiring higher PSRR at RF frequencies, additional local LDO regulation or ferrite-bead filtering on the VCC line is recommended alongside the mandatory 0.1µF ceramic bypass capacitor.
Is MAX4417EUA pin-compatible with other devices in the MAX4414–MAX4419 family?
Yes - all 8-pin variants in the MAX4414–MAX4419 family (including MAX4414EUA, MAX4415EUA, MAX4416EUA, MAX4417EUA, MAX4418EUA, and MAX4419EUA) share identical 8-pin µMAX pinouts. This allows drop-in replacement between unity-gain stable (MAX4414/MAX4416/MAX4418) and gain-of-five stable (MAX4415/MAX4417/MAX4419) versions, provided the application's gain configuration and stability requirements are met. The pin mapping is validated in the "Pin Description" table of the official MAX4414–MAX4419 datasheet.
