Product details
Overview
MAX4186EEE from Maxim Integrated is a dual-channel, current-feedback video amplifier optimized for closed-loop gain ≥+2V/V (6dB), delivering 240MHz small-signal -3dB bandwidth, 70MHz 0.1dB gain flatness, and 450V/µs slew rate on ±5V supplies. It features shutdown mode (135µA per channel), 0.08%/0.03° differential gain/phase error, and 20ns 0.1% settling time - deployed in broadcast HD video routing and CCD imaging front-ends.
For engineers reviewing the MAX4186EEE datasheet, MAX4186EEE pinout, MAX4186EEE application, or MAX4186EEE equivalent, this page provides verified package mapping (16-pin QSOP), validated dual-amplifier pin roles, confirmed video-grade AC performance under AV = +2V/V, and real-world alternative options with documented gain-bandwidth and shutdown compatibility.
Technical Context
The MAX4186EEE implements a current-feedback architecture with high-impedance noninverting input and low-impedance inverting input, enabling stable operation at gains ≥+2V/V without external compensation. Its transresistance gain stage drives up to ±60mA output current into 150Ω loads while maintaining <0.5dB peaking up to 245MHz.
Shutdown control is implemented via two independent logic inputs (SHDNA/SHDNB), each requiring VIH ≥ VCC − 2.0V and VIL ≤ VCC − 3.0V to place respective outputs in high-Z state. Input bias currents are matched within ±1µA (typ), and input voltage range extends to ±3.6V on dual supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4182ESA | Dual-channel, same 16-pin QSOP, but optimized for AV ≥+1V/V (270MHz BW); no shutdown pins | Lacks independent shutdown - unsuitable for dynamic video multiplexing; better for fixed-gain, higher-bandwidth paths | Select when gain ≥+1V/V is acceptable and shutdown is unnecessary; verify stability with RF/RG values per datasheet Table 1 |
| THS3202D | Texas Instruments dual CFA; 375MHz BW, 1200V/µs SR, no shutdown, SO-8 package | Higher speed but larger package and no power management - requires external enable circuitry for multiplexing | Choose for >240MHz bandwidth needs where shutdown is handled externally; confirm layout compatibility with SO-8 footprint |
Compared with MAX4182ESA and THS3202D, the MAX4186EEE uniquely combines dual-channel operation, gain ≥+2V/V stability, integrated shutdown control, and broadcast-grade video specs in a single 16-pin QSOP - making it the only option supporting both high-fidelity HD video routing and low-power portable design without external logic.

FAQ
What is the minimum stable closed-loop gain for MAX4186EEE?
The MAX4186EEE is internally compensated for stable operation at closed-loop gains of +2V/V (6dB) or greater. Attempting to use it at unity gain (AV = +1V/V) may result in peaking or oscillation; for AV = +1V/V applications, select MAX4187EEE instead, which is specifically optimized for that configuration.
Does MAX4186EEE support single-supply operation?
Yes, MAX4186EEE operates from a single +5V supply (VEE = 0V) with input common-mode range of 1.3V to 3.7V and output swing of 1.3V to 3.7V (RL = 1kΩ). Performance metrics such as 210MHz small-signal bandwidth and 50MHz 0.1dB flatness are specified under single-supply conditions.
What is the function of pins 10–16 on MAX4186EEE?
Pins 10 (OUTC), 11 (INC−), 12 (INC+), 14 (IND+), 15 (IND−), and 16 (OUTD) are no-connect (N.C.) in the MAX4186EEE. The MAX4186 is a dual-channel device; these pins correspond to channels C and D used only in the quad-channel MAX4187EEE variant and must remain unconnected.
How does shutdown mode affect output impedance in MAX4186EEE?
When either SHDNA or SHDNB is asserted low, the corresponding amplifier's output enters high-impedance state with leakage current ≤±0.1µA (typ) and disabled output capacitance of 4pF. This allows safe connection of multiple MAX4186EEE outputs to a shared bus without contention or loading effects.
Can MAX4186EEE drive a 75Ω coaxial cable directly?
Yes - MAX4186EEE delivers ±60mA output current, sufficient to drive a 75Ω cable with double termination (75Ω source + 75Ω load). For optimal signal integrity, configure feedback resistors per Table 1 (e.g., RF = RG = 750Ω for AV = +2V/V, RL = 150Ω), ensuring output swing remains within ±3.75V limits.
