Product details
Overview
MAX4390EUK-T from Maxim Integrated is a single-channel, rail-to-rail output voltage-feedback operational amplifier with disable functionality, 85MHz -3dB bandwidth (dual-supply), 500V/µs slew rate, and 0.015% differential gain error-designed for high-fidelity video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4390EUK-T datasheet, MAX4390EUK-T pinout, MAX4390EUK-T application, or MAX4390EUK-T equivalent, this page delivers verified electrical specs, SC70-5 package mapping, disable timing (40ns ON / 80ns OFF), video-grade distortion performance (-59dBc SFDR at 5MHz), and real-world video interface use cases.
Technical Context
The MAX4390EUK-T employs BiCMOS voltage-feedback architecture enhanced with current-feedback techniques to achieve high-speed settling (21ns to 0.1%) while maintaining unity-gain stability. Its input stage accepts common-mode voltages down to VEE and within 2.25V of VCC, enabling robust operation in single-supply video signal chains.
Unlike the MAX4389, the MAX4390EUK-T lacks a dedicated DISABLE pin-confirmed by pin configuration diagrams and Selector Guide-making it a non-shutdown variant optimized for continuous-output applications where low quiescent current (5.5mA) and minimal output impedance (0.6Ω at 5MHz) are prioritized over power gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 85MHz (measured under dual ±5V supply, ensures full NTSC/PAL video spectrum fidelity) |
| Slew Rate | 500V/µs (enables clean 2VP-P large-signal response up to 90MHz without slewing distortion) |
| Differential Gain/Phase Error | 0.015% / 0.015° (NTSC-compliant; eliminates color shift in analog video transmission) |
| Output Drive Capability | ±50mA (drives 75Ω video loads directly without external buffers) |
| Supply Voltage Range | Single 4.5V–11V or dual ±2.25V–±5.5V (supports legacy 5V and modern low-voltage video systems) |
| Input Noise Density | 13nV/√Hz @ 10kHz (preserves SNR in baseband video amplification stages) |
| Quiescent Current | 5.5mA per amplifier (balances speed and power in always-on video signal paths) |
Pinout & Package
The MAX4390EUK-T is housed in a RoHS-compliant 5-pin SOT23 package (package code U5-1), with 0.95mm pitch and 2.9mm × 1.6mm footprint-optimized for space-constrained video module PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Rail-to-rail swing (within 200mV of rails); drives 75Ω video loads directly |
| 2 - VEE | Negative supply | Connect 0.1µF bypass capacitor to ground; supports single-supply (GND) or dual-supply (-5V) operation |
| 3 - IN− | Inverting input | High-impedance node; requires matched trace length and impedance control for video differential pairs |
| 4 - IN+ | Noninverting input | Common-mode range extends to VEE; enables DC-coupled video input in single-supply configurations |
| 5 - VCC | Positive supply | Connect 0.1µF bypass capacitor close to pin; supports 4.5V–11V operation |
Key Features
| Feature | Design Value |
|---|---|

Use Scenario: Active termination and signal boosting in long-run analog video distribution (e.g., security DVR to monitor wall plates). IC Role / Device Role / Timing Role: Unity-gain configured line driver with 75Ω output impedance matching and low capacitive loading sensitivity. Use Value: Optimized for 75Ω Zo systems-output impedance <1Ω at 5MHz minimizes reflections and preserves rise time (<4ns). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4389EUT+T | Identical AC specs but includes DISABLE pin (6-pin SOT23); 5.5mA IS vs. 5.5mA for MAX4390EUK-T | Required where dynamic power gating is needed (e.g., battery-powered portable video recorders) | Select MAX4389EUT+T only if disable functionality is mandatory; otherwise MAX4390EUK-T offers smaller footprint and lower pin count |
| THS3201DGN | Higher slew rate (3100V/µs) and bandwidth (1.8GHz), but higher supply current (12.5mA) and no rail-to-rail output | Better suited for RF IF amplification or pulse applications-not optimized for NTSC/PAL video fidelity | Choose THS3201DGN only for >100MHz wideband signal conditioning; MAX4390EUK-T remains superior for cost-sensitive, video-optimized designs |
Compared with MAX4389EUT+T and THS3201DGN, the MAX4390EUK-T delivers optimal balance of video-grade linearity (0.015% DG), compact 5-pin SOT23 packaging, and proven 75Ω video load drive-without unnecessary complexity or power overhead.

FAQ
What is the supply voltage range supported by the MAX4390EUK-T?
The MAX4390EUK-T operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. This range accommodates both legacy 5V video systems and newer low-voltage designs. The device maintains specified AC performance-including 85MHz bandwidth and 500V/µs slew rate-across the full operating range. Absolute maximum supply voltage is +12V (VCC to VEE).
Does the MAX4390EUK-T include a disable function?
No, the MAX4390EUK-T does not feature a disable function. Unlike the MAX4389EUT+T or MAX4393EUB+T, the MAX4390EUK-T has no DISABLE pin-confirmed by its 5-pin SOT23 pinout and the Selector Guide. It is intended for always-on video signal paths where continuous operation and minimal pin count are priorities.
What is the output drive capability of the MAX4390EUK-T into a 75Ω load?
The MAX4390EUK-T delivers ±50mA output current, enabling direct drive of standard 75Ω video loads. Under 75Ω termination, it sustains rail-to-rail output swing within 200mV of each supply rail and maintains 0.1dB gain flatness to 24MHz-meeting NTSC/PAL requirements. Output impedance is 0.6Ω at 5MHz, minimizing reflection-induced distortion.
How does the MAX4390EUK-T compare to the MAX4389 in terms of video performance?
The MAX4390EUK-T matches the MAX4389's core video performance: identical 0.015% differential gain/phase error, 85MHz bandwidth (dual supply), 500V/µs slew rate, and ±50mA drive. The key distinction is package and functionality-MAX4390EUK-T uses 5-pin SOT23 without disable, while MAX4389EUT+T uses 6-pin SOT23 with disable. Both meet broadcast video fidelity standards.
Is the MAX4390EUK-T suitable for driving ADC inputs in high-speed video acquisition?
Yes, the MAX4390EUK-T is well-suited for driving high-speed video ADC inputs. Its 21ns settling time to 0.1%, low 13nV/√Hz input noise, and ability to deliver full-scale 2VP-P signals with minimal distortion (-59dBc SFDR at 5MHz) ensure accurate sampling. When paired with 75Ω-terminated ADC front-ends, it preserves ENOB and avoids aperture uncertainty in systems up to 40MSPS.
