Product details
Overview
MAX4187EEE+ from Maxim Integrated is a quad-channel, current-feedback operational amplifier optimized for unity-gain (AV ≥ +1) video and high-speed signal conditioning applications. It delivers 270MHz small-signal -3dB bandwidth, 450V/µs slew rate, 20ns settling time to 0.1%, and 0.08%/0.03° differential gain/phase error - enabling broadcast-grade NTSC/PAL video distribution and CCD imaging front-ends.
For engineers reviewing the MAX4187EEE+ datasheet, MAX4187EEE+ pinout, MAX4187EEE+ application, or MAX4187EEE+ equivalent, this page provides verified package mapping (16-pin QSOP), shutdown timing (tON = 50ns, tOFF = 400ns), video-spec compliance (NTSC DG/DP), and direct alternatives with documented gain-bandwidth trade-offs.
Technical Context
The MAX4187EEE+ implements a current-feedback architecture with high-impedance noninverting input and low-impedance inverting input, enabling stable operation at AV ≥ +1 without external compensation. Its transresistance gain stage drives up to ±60mA into 30Ω loads while maintaining 270MHz bandwidth under dual ±5V supplies.
Each of its four amplifiers features independent shutdown control (SHDNA–SHDND), placing outputs in high-impedance state with supply current reduced to 135µA per channel. Input bias currents are ±1µA (typ), and input voltage range extends to ±3.6V on dual supplies - supporting DC-coupled video line drivers and multiplexed A/D buffer interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 270MHz (-3dB, dual ±5V, AV = +1, RL = 150Ω) - supports HD video baseband (1080p60) without gain peaking. |
| Slew Rate | 450V/µs - ensures distortion-free reproduction of fast video transients and pulse signals. |
| Settling Time | 20ns to 0.1% (2V step, RL = 1kΩ) - enables precise timing in high-speed data acquisition and multiplexing. |
| Differential Gain/Phase | 0.08%/0.03° (NTSC, RL = 150Ω) - meets broadcast video fidelity requirements per SMPTE 253M. |
| Supply Current | 1.0mA per amplifier (typ, ±5V) - allows four-channel operation within 4mA total, ideal for portable/battery-powered systems. |
| Shutdown Current | 135µA per amplifier (max) - reduces power by >90% during inactive periods in video switching matrices. |
| Output Drive | ±60mA (RL = 30Ω) - directly drives 75Ω coaxial cables with minimal external buffering. |
Pinout & Package

| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives first video channel or signal path; capable of ±60mA sink/source. |
| 2 | INA− | Inverting input for Amplifier A - low-impedance node for feedback network connection (RF). |
| 3 | INA+ | Noninverting input for Amplifier A - high-impedance, 1.5pF input capacitance; accepts DC- or AC-coupled sources. |

| 13 | VEE | Negative supply rail - connects to −5V (dual) or GND (single); common return for all four amplifiers. |
| 14 | IND+ | Noninverting input for Amplifier D - fourth independent channel input. |
| 15 | IND− | Inverting input for Amplifier D - completes quad-channel current-feedback structure. |

Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Guaranteed for AV ≥ +1 without external compensation - eliminates need for gain-setting resistors in buffer configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3204DGNR | 220MHz bandwidth, 3000V/µs slew rate, no shutdown, 5.5mA IQ per channel | Higher speed but higher power; lacks per-channel shutdown and video-optimized DG/DP specs | Prefer when ultra-fast pulse response dominates over power and video fidelity requirements |
| LMH6723MA/NOPB | 320MHz bandwidth, 1100V/µs slew rate, single-channel, 5.2mA IQ, no shutdown | Higher bandwidth/slew but single-channel only; no integrated shutdown or quad integration | Choose for discrete high-speed buffer stages where board space permits four separate ICs |
Compared with THS3204DGNR and LMH6723MA/NOPB, the MAX4187EEE+ uniquely combines quad integration, per-channel shutdown, broadcast-grade video specs, and ultra-low 1mA/channel quiescent current - making it optimal for space- and power-constrained multi-channel video systems.

FAQ
What supply voltages does the MAX4187EEE+ support?
The MAX4187EEE+ operates from dual ±2.25V to ±5.5V supplies or a single +4.5V to +5.5V rail. With VEE tied to ground, it functions as a single-supply amplifier delivering rail-to-rail compatible output swing (1.3V to 3.7V). Absolute maximum supply voltage is 12V (VCC to VEE), and all specifications are guaranteed across −40°C to +85°C.
Does the MAX4187EEE+ require external compensation for unity-gain operation?
No - the MAX4187EEE+ is internally compensated for stable operation at closed-loop gains of +1 (0dB) or greater. Unlike many current-feedback amplifiers, it does not require external feedback capacitor or resistor networks to prevent oscillation at AV = +1, simplifying PCB layout and reducing bill-of-materials cost in video buffer applications.
How does the shutdown function work on the MAX4187EEE+?
The MAX4187EEE+ provides four independent shutdown inputs (SHDNA–SHDND), one per amplifier. Each channel disables when its SHDN pin falls below (VCC − 3.0V) and enables when above (VCC − 2.0V). In shutdown, output enters high-impedance state and supply current drops to ≤180µA per channel - verified across temperature and supply conditions.
What is the differential gain and phase performance of the MAX4187EEE+?
The MAX4187EEE+ achieves 0.08% differential gain error and 0.03° differential phase error under NTSC conditions (RL = 150Ω), meeting or exceeding SMPTE 253M broadcast video standards. These values are measured at 3.58MHz color subcarrier frequency and confirmed across the full operating temperature range (−40°C to +85°C).
Can the MAX4187EEE+ drive 75Ω coaxial video cables directly?
Yes - the MAX4187EEE+ delivers ±60mA output current into 30Ω loads and maintains 270MHz bandwidth into 150Ω. When configured as a unity-gain buffer with series 75Ω output termination, it fully complies with analog video line-driving requirements, eliminating need for external current-boosting stages in CCTV and broadcast equipment designs.
