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 small-signal bandwidth, 0.1dB gain flatness to 30MHz, and differential gain/phase errors of 0.07%/0.02° - enabling high-fidelity RGB and surveillance video distribution in compact, low-power systems.
For engineers reviewing the MAX4189EEE+ datasheet, MAX4189EEE+ pinout, MAX4189EEE+ application, or MAX4189EEE+ equivalent, this device is selected for high-speed multiplexing, portable video buffering, and professional camera signal conditioning where fast enable/disable (120ns/40ns), low switching transient (110mVp-p), and ±55mA output drive are critical.
Technical Context
The MAX4189EEE+ implements a current-feedback architecture with independent disable control per amplifier channel, enabling high off-isolation (>–55dB) and high-impedance output states during disable mode. Its transresistance-based topology supports stable operation at unity gain while maintaining wide bandwidth and fast settling (28ns to 0.1%).
It operates from ±2.25V to ±5.5V dual supplies or +5V single supply, with rail-to-rail output swing capability into 150Ω loads and input common-mode range extending to ±3.4V. The disable function isolates inputs, places outputs in high-Z, and reduces quiescent current to 450µA per amplifier.

FAQ
What is the maximum operating supply voltage for the MAX4189EEE+?
The MAX4189EEE+ supports a total supply voltage range of ±2.25V to ±5.5V dual supply, or +5V single supply. The absolute maximum rating is ±6V (12V total), but operation beyond ±5.5V risks reliability degradation. For single-supply use, VEE must be connected to GND and VCC to +5V, with input common-mode range centered at VCC/2.
Does the MAX4189EEE+ support DC-coupled video applications?
Yes, the MAX4189EEE+ supports DC-coupled video applications. Its input common-mode voltage range extends from ±3.1V (guaranteed) to ±3.4V (typical), and output swing reaches within 1.15V of rails into 1kΩ and 1.4V into 150Ω. This enables direct coupling of baseband video signals without AC-blocking capacitors, preserving low-frequency content and reducing component count.
What is the disable behavior of the MAX4189EEE+ outputs?
When disabled, each amplifier in the MAX4189EEE+ isolates its inputs, places its output in a high-impedance state (not clamped), and reduces quiescent supply current to 450µA per amplifier. Output leakage remains below ±5µA at ±3.5V, ensuring no unintended loading of downstream circuitry during disable - critical for video multiplexer architectures.
How does the MAX4189EEE+ compare to the MAX4190 in terms of bandwidth and gain configuration?
The MAX4189EEE+ is a triple amplifier optimized for AV ≥ +1V/V with 250MHz bandwidth, while the MAX4190 is a single amplifier optimized for AV ≥ +2V/V with 185MHz bandwidth. The MAX4189EEE+ supports unity-gain stability and higher channel density; the MAX4190 offers lower distortion at +2V/V but cannot operate stably at unity gain without external compensation.
Can the MAX4189EEE+ drive 75Ω video loads directly?
Yes, the MAX4189EEE+ can drive 75Ω video loads directly. It delivers ±55mA output current and maintains 0.07% differential gain error into 1kΩ and 0.18% into 150Ω loads - indicating robust drive capability into standard 75Ω terminated lines. Layout best practices (short traces, proper termination, ground plane) are recommended to preserve signal integrity at full bandwidth.
