Product details
Overview
MAX4187ESD+TG074 from Maxim Integrated is a quad-channel, current-feedback video amplifier optimized for +1V/V (0dB) gain applications. It delivers 270MHz small-signal bandwidth, 450V/µs slew rate, and 0.08%/0.03° differential gain/phase error, enabling high-fidelity analog video signal conditioning in broadcast-grade CCD imaging and HD surveillance systems.
For engineers reviewing the MAX4187ESD+TG074 datasheet, MAX4187ESD+TG074 pinout, MAX4187ESD+TG074 application, or MAX4187ESD+TG074 equivalent, key selection criteria include its 16-pin QSOP package, dual ±5V or single +5V operation, shutdown-enabled multiplexing capability, and verified performance in NTSC video paths with <21ns settling time and -73dBc SFDR at 5MHz.
Technical Context
The MAX4187ESD+TG074 implements a current-feedback architecture with transresistance gain stage, supporting stable unity-gain operation without external compensation. Its input stage features matched high-impedance positive and negative inputs (RIN+ = 160Ω, RIN− = 250–800kΩ), enabling precise differential video signal handling.
Each of its four amplifiers integrates independent shutdown control (SHDNA–SHDND), reducing quiescent current to 135µA per channel while placing outputs in high-impedance state. The device maintains 60MHz 0.1dB bandwidth and 20–22ns settling time across all channels under RL = 1kΩ load conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4186ESD+ | Optimized for AV ≥ +2V/V (6dB); 240MHz bandwidth, 70MHz 0.1dB flatness | Requires minimum closed-loop gain of +2; unsuitable for unity-gain video line drivers | Select MAX4186ESD+ only when fixed +2V/V gain is acceptable and higher DC precision is needed |
| THS3201DGN | Single-channel, 1.8GHz bandwidth, 3000V/µs slew rate; no integrated shutdown | Lacks per-channel power control; requires external logic for multiplexing; higher power (12mA) | Choose THS3201DGN for ultra-wideband RF/video hybrid applications where shutdown is not required |
Compared with MAX4186ESD+ and THS3201DGN, the MAX4187ESD+TG074 uniquely combines quad-channel integration, unity-gain stability, per-amplifier shutdown, and broadcast-grade video specs in a single 16-pin QSOP - making it optimal for space-constrained, multi-source analog video systems requiring low-power, high-fidelity signal conditioning.

FAQ
What is the operating supply voltage range for MAX4187ESD+TG074?
The MAX4187ESD+TG074 operates from ±2.25V to ±5.5V dual supplies or a single +5V supply. In single-supply mode, VEE is connected to ground and VIN+ is biased at VCC/2 (2.5V). This flexibility allows integration into both legacy ±5V video infrastructure and modern 5V-only embedded systems without level-shifting circuitry.
Does MAX4187ESD+TG074 support unity-gain stable operation?
Yes, the MAX4187ESD+TG074 is internally compensated for applications with closed-loop gain of +1V/V (0dB) or greater. Unlike the MAX4186ESD+, which requires minimum +2V/V gain, the MAX4187ESD+TG074 can be configured as a unity-gain buffer - essential for video line driving where gain preservation is critical.
What is the shutdown behavior of MAX4187ESD+TG074?
Each of the four amplifiers in MAX4187ESD+TG074 has an independent shutdown pin (SHDNA–SHDND). When pulled ≤(VCC − 3V), the corresponding amplifier reduces supply current to 135µA and places its output in high-impedance state - enabling selective channel disabling in video multiplexers without affecting other active channels.
How does MAX4187ESD+TG074 perform in NTSC video applications?
The MAX4187ESD+TG074 achieves 0.08% differential gain error and 0.03° differential phase error under NTSC conditions (RL = 150Ω), meeting broadcast-quality standards. Its 60MHz 0.1dB bandwidth and 21ns settling time ensure accurate reproduction of luminance/chrominance timing relationships in composite video signals.
What package type is used for MAX4187ESD+TG074?
MAX4187ESD+TG074 uses a 16-pin QSOP package (5.3mm × 10.2mm, 0.635mm pitch) with exposed pad for thermal enhancement. This surface-mount package supports automated assembly and provides adequate power dissipation (667mW at +70°C) for continuous video signal conditioning in compact enclosures.
