Product details
Overview
MAX4395EUD+ from Analog Devices is a triple-channel, rail-to-rail output, unity-gain stable voltage-feedback op amp with disable functionality, 85MHz -3dB bandwidth, 500V/μs slew rate, and 0.015% differential gain error. It operates from single 4.5V–11V or dual ±2.25V–±5.5V supplies and targets high-fidelity video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4395EUD+ datasheet, MAX4395EUD+ pinout, MAX4395EUD+ application, or MAX4395EUD+ equivalent, key selection criteria include its triple-amplifier architecture with per-channel disable, 14-pin TSSOP package, 27MHz 0.1dB gain flatness, low-distortion video performance (−59dBc SFDR at 5MHz), and compatibility with 75Ω video loads.
Technical Context
The MAX4395EUD+ integrates three independent amplifiers in a single 14-pin TSSOP package, each featuring current-feedback-enhanced voltage-feedback topology to achieve high slew rate and wide bandwidth while maintaining DC precision. Its input common-mode range extends to VEE (ground in single-supply mode), and outputs swing within 200mV of both rails under 150Ω load.
Each amplifier includes a dedicated DISABLE pin (pins 4, 10, 13) enabling independent high-impedance shutdown with only 450μA quiescent current per channel. The device uses BiCMOS process technology and requires local 0.1μF supply bypassing at VCC (pin 1) and VEE (pin 8) for stable RF/video operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-channel video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3203DR | Single-channel, no disable function; higher 1.4GHz GBW but higher 15mA quiescent current per amp. | Lacks integrated triple-channel + disable; requires three separate packages and external logic for power gating. | Choose THS3203DR only if >1GHz bandwidth is required and board space/power budget allow discrete implementation. |
| LMH6738MQX/NOPB | Dual-channel only; no per-amplifier disable; 1.3GHz bandwidth but 12mA supply current per amp. | Requires two devices plus external OR-ing logic to match MAX4395EUD+'s triple-channel + disable capability. | Select LMH6738MQX/NOPB when dual-channel operation suffices and ultra-wideband (>500MHz) is prioritized over power efficiency. |
Compared with THS3203DR and LMH6738MQX/NOPB, the MAX4395EUD+ delivers integrated triple-channel operation with per-amplifier disable in a single 14-pin TSSOP, reducing PCB area by 60% and cutting total quiescent power by 55% in always-on video systems.

FAQ
What is the operating supply voltage range for the MAX4395EUD+?
The MAX4395EUD+ operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. This wide range supports compatibility with legacy 5V video systems and modern low-voltage embedded platforms. The device guarantees specified AC performance across this entire range, including 85MHz bandwidth and 0.015% differential gain error at both 5V and ±5V conditions. Internal BiCMOS circuitry ensures stable biasing regardless of supply configuration.
Does the MAX4395EUD+ support rail-to-rail input common-mode voltage?
The MAX4395EUD+ supports rail-to-rail output swing but not rail-to-rail input common-mode range. Its input common-mode voltage extends to the negative supply rail (VEE) and up to VCC − 2.25V. In single-supply 5V operation, this means inputs can range from 0V to 2.75V - sufficient for DC-coupled video signals referenced to ground. This design balances input headroom with high-speed performance and is validated in all video applications listed in the official datasheet.
How does the disable function work on the MAX4395EUD+?
The MAX4395EUD+ features three independent DISABLE pins (pins 4, 10, 13) - one per amplifier. Driving a DISABLE pin low (≤VCC − 3V) places that amplifier's output in high-impedance state (≥40kΩ) while reducing its quiescent current to 450μA. This allows dynamic power management in multi-channel video systems - for example, disabling unused RGB channels during monochrome mode. The 40ns enable and 80ns disable times ensure glitch-free switching synchronized to video blanking intervals.
Can the MAX4395EUD+ drive a 75Ω video load directly?
Yes, the MAX4395EUD+ is explicitly characterized to drive 75Ω video loads with full performance. Each amplifier delivers ±50mA output current and maintains 0.015% differential gain error into 150Ω loads - which translates to robust 75Ω drive capability with margin. The datasheet includes typical operating circuits for 75Ω video line driving, and the 200mV output swing limitation at 150Ω confirms ≥4.6VPP swing into 75Ω at 5V supply - meeting SMPTE and ITU-R broadcast standards without external components.
What is the thermal performance of the MAX4395EUD+ in its 14-pin TSSOP package?
The MAX4395EUD+ in 14-pin TSSOP has a junction-to-ambient thermal resistance (θJA) of 100.4°C/W on multilayer PCBs. At maximum rated 5.5mA per amplifier (16.5mA total) and 5V supply, power dissipation is ~82.5mW, resulting in ~8.3°C junction-to-ambient rise above ambient - well within the −40°C to +85°C operating range. The package's exposed pad variant is not offered; standard TSSOP layout guidelines (2oz copper, thermal vias under pad) are recommended for sustained video line driving at full bandwidth.
