Product details
Overview
The MAX4189EEE from Maxim Integrated is a triple, current-feedback video amplifier optimized for closed-loop gains ≥+1V/V (0dB), delivering 250MHz -3dB bandwidth, 0.1dB gain flatness to 30MHz, and differential gain/phase errors of 0.07%/0.02° - enabling high-fidelity RGB distribution and HD surveillance video signal conditioning.
For engineers reviewing the MAX4189EEE datasheet, MAX4189EEE pinout, MAX4189EEE application, or MAX4189EEE equivalent, this device is selected for low-glitch, high-speed multiplexing in portable multimedia systems where fast enable/disable (120ns/40ns), ±55mA output drive, and 1.5mA/quiescent supply current are critical design constraints.
Technical Context
The MAX4189EEE implements a current-feedback architecture with independent disable control per amplifier channel, enabling high off-isolation (>–55dB) and low switching transients (110mVp-p). Its transresistance gain stage provides wide bandwidth stability across gain ≥+1V/V without external compensation.
Each amplifier features rail-to-rail output swing into 150Ω loads, operates from ±2.25V to ±5.5V dual supplies or +5V single supply, and maintains 22ns settling to 0.1% with 175V/µs slew rate at AV = +1V/V - supporting high-speed analog-to-digital buffering and CCD imaging front-ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4188EEE+ | Triple amplifier optimized for AV ≥ +2V/V; 200MHz bandwidth, 350V/µs slew rate | Better suited for fixed-gain +2 video line drivers; not optimized for unity-gain stable operation | Select when gain ≥ +2V/V is required and higher slew rate outweighs bandwidth trade-off |
| THS3201CD | Single-channel, 1.8GHz bandwidth, 6000V/µs slew rate, 12.5mA supply current | Higher power, wider bandwidth - used in RF sampling and wideband test equipment, not video distribution | Select only for ultra-high-speed applications beyond video; not drop-in due to pinout, power, and disable logic differences |
Compared with MAX4188EEE+ and THS3201CD, the MAX4189EEE uniquely balances triple-channel integration, unity-gain stability, low power, and video-optimized distortion performance - making it the preferred choice for portable HD video routing where channel count, power, and fidelity must coexist.

FAQ
What is the operating supply voltage range for the MAX4189EEE?
The MAX4189EEE operates from ±2.25V to ±5.5V dual supplies or a single +5V supply. It supports rail-split operation (VEE = 0V) with input common-mode range of ±3.1V and output swing to within 1.15V of rails into 150Ω - enabling compatibility with both legacy analog video and modern low-voltage embedded systems. The MAX4189EEE maintains specified performance across the full –40°C to +85°C industrial temperature range.
Does the MAX4189EEE support unity-gain stable operation?
Yes, the MAX4189EEE is explicitly optimized for closed-loop gains of +1V/V (0dB) or greater, with guaranteed 250MHz –3dB bandwidth and 30MHz 0.1dB gain flatness at AV = +1V/V. Unlike the MAX4188EEE+, which requires AV ≥ +2V/V for stability, the MAX4189EEE uses internal compensation tailored for unity-gain video distribution - confirmed by datasheet AC performance tables and typical gain-vs-frequency plots under AV = +1V/V conditions.
How does the disable functionality work on the MAX4189EEE?
The MAX4189EEE provides three independent DISABLE pins (pins 1, 5, 9) - each controlling one amplifier channel. When a DISABLE pin is pulled ≤(VCC – 3V), that amplifier's inputs are isolated, its output enters high-impedance state, and quiescent current drops to 450µA. Enable occurs when DISABLE ≥(VCC – 2V). This allows selective channel muting in RGB systems without affecting other active channels - a key feature for the MAX4189EEE in video multiplexing applications.
What is the differential gain and phase performance of the MAX4189EEE?
The MAX4189EEE delivers 0.07% differential gain error and 0.02° differential phase error under NTSC conditions (RL = 1kΩ, f = 10kHz), meeting broadcast-quality video specifications. These values are measured at AV = +1V/V and confirm the MAX4189EEE's suitability for professional RGB, YUV, and component video routing where color fidelity and timing alignment are critical - outperforming many general-purpose op-amps in video-specific metrics.
Is the MAX4189EEE pin-compatible with other devices in the MAX4188 family?
No, the MAX4189EEE is not pin-compatible with the MAX4188EEE+ or MAX4190. All three share the same 16-pin QSOP footprint, but pin functions differ: MAX4188EEE+ has three DISABLE pins (1, 8, 15), while MAX4189EEE uses pins 1, 5, 9; MAX4190 is an 8-pin µMAX device. Layout reuse requires verification against each device's specific pinout - the MAX4189EEE's unique DISABLE placement reflects its triple-channel, unity-gain-optimized architecture.
