Product details
Overview
MAX4187ESD+ from Maxim Integrated is a single-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, and 20ns settling time to 0.1%, with ultra-low 1mA quiescent supply current per amplifier and integrated shutdown control. It operates from ±2.25V to ±5.5V dual supplies or +5V single supply, and is housed in a 16-pin QSOP package.
For engineers reviewing the MAX4187ESD+ datasheet, MAX4187ESD+ pinout, MAX4187ESD+ application, or MAX4187ESD+ equivalent, this page provides verified circuit role, pin-confirmed terminal functions, real-world video-system design values (e.g., 0.08%/0.03° differential gain/phase error at NTSC), and validated alternative options for multiplexed HD video buffering and CCD imaging front-ends.
Technical Context
The MAX4187ESD+ uses a current-feedback architecture with high-impedance noninverting input and low-impedance inverting input, enabling stable operation at AV = +1V/V without external compensation. Its transresistance gain stage drives up to ±60mA output current into 30Ω loads while maintaining 0.08% differential gain accuracy across 70MHz.
Shutdown functionality reduces supply current to 135µA and places outputs in high-impedance state-critical for analog video switching matrices. Input bias currents are ±1µA (typ), input noise voltage is 2nV/√Hz, and it achieves -73dBc SFDR at 5MHz with 2Vp-p output into 150Ω.

Use Scenario: Analog HD-over-Coax (AHD/CVI/TVI) camera sensor interface with real-time analog signal conditioning prior to digitization. IC Role / Device Role / Timing Role: Single MAX4187ESD+ channel acts as DC-coupled video buffer and driver between CMOS image sensor and ADC, providing gain, drive strength, and common-mode level shift. Use Value: 20ns settling ensures accurate pixel sampling at 1080p60; 0.08% differential gain preserves color fidelity across wide temperature range (-40°C to +85°C). |
Use Scenario: 4×1 analog video switcher for security DVR/NVR systems requiring simultaneous display of multiple camera feeds. IC Role / Device Role / Timing Role: All four amplifiers operate independently, each driving one camera channel; SHDN pins enable zero-crossing mute during channel switching. Use Value: 135µA shutdown current minimizes system standby power; crosstalk < -60dB prevents ghosting between active channels. |
| Medical Endoscope Signal Chain | CCD Line-Scan Imaging System |
|
Use Scenario: High-resolution endoscopic video processing where EMI immunity and signal integrity are critical in compact handheld units. IC Role / Device Role / Timing Role: MAX4187ESD+ serves as post-amplifier after analog gamma correction, delivering clean, low-noise video to embedded encoder ASIC. Use Value: 2nV/√Hz input noise density and 450V/µs slew rate preserve fine tissue detail and edge sharpness in real-time surgical video. |
Use Scenario: Industrial line-scan CCD camera used in PCB inspection, where precise analog pixel timing and amplitude stability are essential. IC Role / Device Role / Timing Role: One amplifier channel conditions CCD analog output; others buffer sync signals (HSYNC, VSYNC, CLK) with matched propagation delay. Use Value: Gain matching to 0.1dB up to 25MHz ensures consistent pixel amplitude across entire scan line; 270MHz bandwidth accommodates high-speed clock harmonics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DGNR | Higher 1.8GHz GBW but 12mA IQ; no shutdown; SO-8 package only | Lacks integrated shutdown and quad-channel integration; requires external disable circuitry | Prefer THS3201DGNR only when >1GHz bandwidth is mandatory and power budget allows 12× higher IQ |
| LMH6720MF/NOPB | 220MHz bandwidth, 3.5mA IQ, no shutdown, SOT-23-6 single-channel only | Single-channel only; no multi-amp integration; lower bandwidth limits 1080p60 support | Select LMH6720MF/NOPB for cost-sensitive single-channel designs where 220MHz suffices and layout space is constrained |
Compared with THS3201DGNR and LMH6720MF/NOPB, the MAX4187ESD+ uniquely combines quad-channel integration, 270MHz bandwidth, 1mA quiescent current, and hardware shutdown in a single 16-pin QSOP-making it optimal for space- and power-constrained multi-channel HD video systems where channel coordination and low standby power are design priorities.

FAQ
What is the operating supply voltage range for the MAX4187ESD+?
The MAX4187ESD+ operates from ±2.25V to ±5.5V dual supplies or from a single +5V supply. When using single-supply mode, VEE must be connected to ground, and the input common-mode range is specified from 1.1V to 3.9V. The device maintains full performance-including 270MHz bandwidth and 0.08% differential gain accuracy-across this entire supply range. Absolute maximum supply voltage is 12V (VCC to VEE).
Does the MAX4187ESD+ require external compensation for unity-gain operation?
No, the MAX4187ESD+ is internally compensated for stable operation at AV ≥ +1V/V. Unlike many current-feedback amplifiers that require external feedback resistors and compensation capacitors for unity-gain stability, the MAX4187ESD+ achieves this without added components-simplifying layout and reducing bill-of-materials cost in video line drivers and buffer stages.
How does the shutdown feature of the MAX4187ESD+ behave electrically?
When the SHDN pin is driven ≤(VCC − 3V), the MAX4187ESD+ enters shutdown mode: quiescent supply current drops to 135µA (typ), and all four amplifier outputs enter high-impedance state. Output leakage remains ±0.1µA (max). The turn-off time is 400ns, and turn-on time is 50ns-enabling sub-microsecond channel muting in video switchers without visible artifacts.
What is the differential phase and gain error specification of the MAX4187ESD+ under NTSC conditions?
Under NTSC video conditions with 150Ω load, the MAX4187ESD+ achieves 0.08% differential gain error and 0.03° differential phase error. These values are measured at standard video frequencies and confirm compliance with broadcast-quality video standards such as SMPTE 259M. Performance is maintained across the full operating temperature range of −40°C to +85°C.
Can the MAX4187ESD+ drive a 75Ω coaxial cable directly?
Yes-the MAX4187ESD+ can drive a 75Ω coaxial cable directly when configured with proper termination. With ±60mA output current capability and 4.8Ω output impedance, it supports double-terminated 75Ω lines (e.g., 75Ω series resistor at source + 75Ω shunt at load), delivering full swing without clipping. For best signal integrity, use RF-optimized PCB layout and maintain controlled impedance traces.
