Product details
Overview
The MAX4189ESD+ 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° under NTSC conditions with 150Ω load. 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 HD surveillance video routing.
For engineers reviewing the MAX4189ESD+ datasheet, MAX4189ESD+ pinout, MAX4189ESD+ application, or MAX4189ESD+ equivalent, this page provides verified specifications including disable timing, video distortion metrics (SFDR = 65dB at 5MHz), output drive capability (±55mA), and package-specific thermal derating - all critical for multiplexer design, portable video systems, and analog-to-digital buffer staging.
Technical Context
The MAX4189ESD+ implements a current-feedback architecture enabling wide bandwidth independent of closed-loop gain, with transresistance gain set by external feedback resistors (e.g., RF = 1600Ω, RG = 1100Ω for RL = 150Ω). Its disable control isolates inputs, places outputs in high-impedance state, and reduces quiescent current to 450µA per amplifier while maintaining >55dB off-isolation up to 100MHz.
Designed for video signal integrity, it achieves 0.07% differential gain error and 0.02° phase error at NTSC frequencies with 150Ω load, supported by 22ns settling time to 0.1%, 175V/µs slew rate (AVCL = +1V/V), and low 2nV/√Hz input voltage noise - ensuring minimal color fidelity loss in professional camera and CCD imaging systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4188ESD+ | Triple amplifier optimized for AVCL ≥ +2V/V; 200MHz bandwidth; 0.03%/0.05° DG/DP | Better suited for fixed-gain +2V/V video lines (e.g., composite video), not unity-gain RGB | Select MAX4188ESD+ only when closed-loop gain is ≥+2V/V and lower differential phase error is required |
| THS3201CD | Single-channel, 1.8GHz bandwidth, 3000V/µs slew rate; higher power (12.5mA/ch), no disable function | Targeted at ultra-high-speed test equipment or RF IF stages, not video multiplexing | Choose THS3201CD only for non-video, high-frequency (>500MHz) analog signal paths requiring extreme speed |
Compared with MAX4188ESD+, the MAX4189ESD+ delivers 25% higher bandwidth at unity gain and lower differential gain error for RGB, while THS3201CD offers vastly higher speed but lacks disable control and consumes 8× more power - making MAX4189ESD+ optimal for power-constrained, multi-channel video routing.

FAQ
What is the maximum operating temperature range for the MAX4189ESD+?
The MAX4189ESD+ is specified for operation from -40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in HD surveillance enclosures, portable medical devices, and broadcast equipment subject to thermal cycling. The 14-pin SO package (S14-1) maintains electrical characteristics across this full range, with supply current varying only ±0.15mA per amplifier from min to max temperature.
Does the MAX4189ESD+ support single-supply operation?
Yes, the MAX4189ESD+ supports single-supply operation with VCC = +5V and VEE tied to ground. In this configuration, it delivers 230MHz -3dB bandwidth (AVCL = +1V/V, RL = 150Ω), 0.1dB gain flatness to 40MHz, and maintains 0.06%/0.07° differential gain/phase error under NTSC conditions. Input common-mode range spans 1.5V to 3.5V, allowing direct interface with 2.5V-referenced video DACs.
What is the disable threshold voltage for the MAX4189ESD+?
The MAX4189ESD+ DISABLE pins have guaranteed thresholds of VIL ≤ VCC − 3V (disable active) and VIH ≥ VCC − 2V (enable active), with typical values of 1.8V and 2.8V respectively at VCC = +5V. This TTL-compatible interface allows direct connection to FPGA GPIOs or microcontroller outputs without level-shifting, and ensures robust noise immunity with 1V hysteresis.
How does the MAX4189ESD+ compare to the MAX4188ESD+ in video performance?
The MAX4189ESD+ is optimized for AVCL ≥ +1V/V with 250MHz bandwidth and 0.07%/0.02° DG/DP (RL = 150Ω), while the MAX4188ESD+ targets AVCL ≥ +2V/V with 200MHz bandwidth and superior 0.03%/0.05° DG/DP. For RGB distribution (unity gain), MAX4189ESD+ provides wider bandwidth and lower phase error; for composite video (+2V/V), MAX4188ESD+ offers better color fidelity.
Can the MAX4189ESD+ drive 75Ω coaxial cables directly?
Yes, the MAX4189ESD+ can drive 75Ω coaxial cables directly when configured for AVCL = +1V/V with appropriate feedback network (e.g., RF = 1600Ω, RG = 1100Ω). It delivers 0.07% differential gain error and maintains >55dB off-isolation up to 100MHz - meeting SMPTE 259M requirements for SD-SDI cable driving. Termination must be implemented at the load end to prevent reflections.
