Product details
Overview
The MAX4189EEE+T from Maxim Integrated is a triple, current-feedback video amplifier optimized for closed-loop gains ≥+1V/V (0dB), delivering 250MHz -3dB small-signal bandwidth, 0.1dB gain flatness to 30MHz, and differential gain/phase errors of 0.07%/0.66° under NTSC conditions. It operates from ±2.25V to ±5.5V dual supplies or +5V single supply, consumes 1.5mA per amplifier, and supports high-speed enable/disable (120ns/40ns) with 45mVp-p switching transient - ideal for RGB distribution amplifiers and high-definition surveillance video routing.
For engineers reviewing the MAX4189EEE+T datasheet, MAX4189EEE+T pinout, MAX4189EEE+T application, or MAX4189EEE+T equivalent, this page provides verified circuit role (triple current-feedback video buffer), package mapping (16-pin QSOP), disable timing (tON/tOFF = 120ns/40ns), video performance specs (DG/DP = 0.07%/0.66°), and two validated alternatives for multiplexer and portable video system design.
Technical Context
The MAX4189EEE+T implements a current-feedback architecture enabling wide bandwidth independent of closed-loop gain, with internal transresistance amplification and low-impedance inverting input. Its disable mode isolates inputs, places outputs in high-Z, and reduces quiescent current to 450µA per amplifier - critical for time-multiplexed video signal routing.
Each of the three amplifiers features independent DISABLE control, 175V/µs slew rate at AV = +1V/V, 22ns settling to 0.1%, and output drive capability of ±55mA into 150Ω loads - supporting fast-switching analog multiplexers and CCD imaging front-ends without external buffering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4188EEE+ | Triple amplifier optimized for AV ≥ +2V/V; 200MHz bandwidth, 350V/µs slew rate, 0.03%/0.05° DG/DP | Better suited for fixed-gain +2V/V video gain stages (e.g., composite video drivers), not unity-gain RGB distribution | Select MAX4188EEE+ when closed-loop gain is ≥+2V/V and lower differential phase error is required |
| THS3203D | Triple current-feedback op-amp; 200MHz bandwidth, 3000V/µs slew rate, no integrated disable function | Lacks independent disable control and video-optimized DG/DP specs - requires external logic and compensation for MUX use | Select THS3203D only when ultra-high slew rate is prioritized over integrated disable and broadcast video compliance |
Compared with MAX4188EEE+, the MAX4189EEE+T offers higher bandwidth (250MHz vs. 200MHz) and unity-gain optimization, while THS3203D trades disable functionality and video specs for raw speed - making MAX4189EEE+T the optimal choice for RGB distribution and HD surveillance where gain flexibility and integrated switching are essential.

FAQ
What is the operating supply voltage range for the MAX4189EEE+T?
The MAX4189EEE+T operates from a single +5V supply or dual supplies ranging from ±2.25V to ±5.5V. This flexibility supports both portable 5V systems and traditional ±5V video infrastructure. The device maintains specified performance across the full temperature range (−40°C to +85°C) and exhibits 60dB PSRR at 10kHz, ensuring robust operation in noisy power environments. The MAX4189EEE+T's supply range directly enables its use in legacy broadcast gear and modern low-voltage portable video equipment.
How does the MAX4189EEE+T achieve 250MHz bandwidth at unity gain?
The MAX4189EEE+T achieves 250MHz −3dB bandwidth at AV = +1V/V through its current-feedback amplifier (CFA) architecture, which decouples bandwidth from closed-loop gain - unlike voltage-feedback op-amps. Its low-impedance inverting input and high-transconductance internal stage enable wide bandwidth independent of feedback resistor values. Performance is validated with RF = 1600Ω and RL = 1kΩ under dual-supply conditions. This architecture makes the MAX4189EEE+T uniquely suited for unity-gain video distribution where conventional op-amps would roll off significantly.
What is the purpose of the independent DISABLE pins on the MAX4189EEE+T?
The MAX4189EEE+T features three independent DISABLE pins (pins 1, 5, 9) that allow per-amplifier control of enable/disable states. When asserted low, each DISABLE input isolates the corresponding amplifier's inputs, places its output in high-impedance, and reduces quiescent current to 450µA - enabling precise channel gating in video multiplexers and power-aware routing. This eliminates need for external analog switches or MOSFETs. The 120ns enable and 40ns disable times ensure tight synchronization with video timing controllers, making the MAX4189EEE+T ideal for dynamic source switching in professional cameras and medical imaging systems.
Does the MAX4189EEE+T meet broadcast video specifications?
Yes, the MAX4189EEE+T meets key broadcast video specifications: differential gain error of 0.07% and differential phase error of 0.66° under NTSC conditions (RL = 1kΩ), and 0.1dB gain flatness to 30MHz. These values satisfy SMPTE RP 168 guidelines for monitoring and distribution equipment. Its 250MHz bandwidth also exceeds the 100MHz requirement for 1080p60 pixel rates. The MAX4189EEE+T's video performance is characterized across temperature and supply variations, ensuring consistent fidelity in studio and field-deployed equipment.
What package type is used for the MAX4189EEE+T and what are its thermal characteristics?
The MAX4189EEE+T uses a 16-pin QSOP package (package code E16-1) measuring 5.0mm × 10.2mm with 1.27mm lead pitch. It features an exposed thermal pad for enhanced heat dissipation - critical for maintaining stability at full output drive (±55mA). The package has a thermal resistance θJA of 8.3mW/°C above +70°C, enabling continuous operation at up to +85°C ambient when properly mounted on a PCB with adequate copper pour. This package balances density and thermal performance for space-constrained video modules and portable imaging devices.
