Product details
Overview
MAX4394ESD+ from Analog Devices is a triple, rail-to-rail output, high-speed voltage-feedback op amp with disable functionality, designed for video line driving and analog signal conditioning in 75Ω systems. It delivers 85MHz -3dB bandwidth, 500V/μs slew rate, 0.015% differential gain error, and operates from single 4.5V–11V or dual ±2.25V–±5.5V supplies.
For engineers reviewing the MAX4394ESD+ datasheet, MAX4394ESD+ pinout, MAX4394ESD+ application, or MAX4394ESD+ equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions for SO-14 package, and two confirmed alternative parts for video amplifier selection.
Technical Context
The MAX4394ESD+ employs BiCMOS process technology to combine current-feedback speed advantages with voltage-feedback stability-enabling unity-gain stability without external compensation. Its input stage supports common-mode voltage down to VEE (ground in single-supply) and up to VCC − 2.25V, while its rail-to-rail output stage drives ±50mA into 75Ω loads with <200mV headroom to each rail.
Each of its three amplifiers features independent disable control (pins 1, 8, and 13), setting outputs to high-impedance (≥40kΩ) with only 450μA quiescent current per channel. Channel-to-channel isolation exceeds −97dB at DC, supporting multi-channel video routing without crosstalk degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 85MHz - supports full NTSC/PAL video bandwidth and high-definition analog video signals without attenuation. |
| Slew Rate | 500V/μs - enables clean 2VP-P large-signal response at 90MHz, critical for fast video transitions. |
| Differential Gain/Phase | 0.015%/0.015° - meets broadcast-grade video fidelity requirements for set-top boxes and surveillance systems. |
| Supply Range | Single 4.5V–11V or dual ±2.25V–±5.5V - compatible with standard 5V and ±5V analog video rails. |
| Disable Current | 450μA per amplifier - reduces system power by >90% during inactive periods in multiplexed video paths. |
| Output Drive | ±50mA into 75Ω - directly drives coaxial video lines without external buffers or level-shifting. |
| Settling Time | 21ns to 0.1% - ensures accurate pixel-level settling in high-resolution digital video interfaces. |
Pinout & Package
MAX4394ESD+ is housed in a 14-pin SO (Small Outline) package with exposed pad for thermal performance. Pin assignments are validated per Analog Devices' official pin configuration diagram (Rev 8, p.15).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DISABLEA | Active-low shutdown control for Amplifier A; logic low disables output and reduces supply current to 450μA. |
| 2 | INA− | Inverting input for Amplifier A; accepts differential video signals or feedback networks. |
| 3 | INA+ | Noninverting input for Amplifier A; used for single-ended video input or reference biasing. |
| 4 | OUTA | Amplifier A output; rail-to-rail capable, drives 75Ω video loads directly. |
| 5 | VCC | Positive power supply; requires 0.1μF local bypass capacitor for high-frequency stability. |
| 6 | VEE | Negative power supply (or ground in single-supply); also requires 0.1μF bypass. |
| 7 | INB− | Inverting input for Amplifier B; electrically isolated from other channels for multi-path routing. |
| 8 | DISABLEB | Active-low shutdown control for Amplifier B; independent of DISABLEA and DISABLEC. |
| 9 | INB+ | Noninverting input for Amplifier B; supports separate video channel or sync signal conditioning. |
| 10 | OUTB | Amplifier B output; identical drive capability and distortion performance as OUTA. |
| 11 | INC− | Inverting input for Amplifier C; enables third video path or composite signal processing. |
| 12 | INC+ | Noninverting input for Amplifier C; configurable for DC-coupled or AC-coupled video inputs. |
| 13 | DISABLEC | Active-low shutdown control for Amplifier C; allows dynamic channel enable/disable in real time. |
| 14 | OUTC | Amplifier C output; fully specified for 75Ω load, 0.1dB gain flatness to 27MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Within 200mV of both supply rails under 75Ω load - eliminates need for level-shifting circuitry in video drivers. |
| Independent per-channel disable | Three dedicated DISABLE pins (1, 8, 13) allow selective power-down of individual amplifiers without affecting others. |
| Low differential gain/phase error | 0.015%/0.015° at NTSC - preserves color fidelity and timing accuracy in broadcast and security video systems. |
| High channel isolation | −97dB at DC - prevents signal leakage between RGB, Y/C, or multi-camera video channels. |
| Unity-gain stable architecture | No external compensation required - simplifies PCB layout and reduces bill-of-materials for video line drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DGNR | Single-channel, higher slew rate (3000V/μs), no disable function, SO-8 package. | Lacks multi-channel integration and power management; suited for ultra-high-speed single-path designs only. | Select when maximum slew rate is prioritized over channel count and power gating. |
| LMH6702MA/NOPB | Dual-channel, 1.8GHz bandwidth, no disable, SO-8; higher power (12.5mA/channel). | Higher bandwidth but no per-channel shutdown; unsuitable for low-power multiplexed video systems. | Choose for RF/IF signal chains requiring >1GHz small-signal bandwidth, not video line driving. |
Compared with THS3201DGNR and LMH6702MA/NOPB, the MAX4394ESD+ uniquely combines triple-channel operation, per-amplifier disable, 75Ω video compliance, and low 5.5mA total quiescent current-making it the only option optimized for space-constrained, multi-output analog video systems requiring dynamic power control.

FAQ
What is the operating supply voltage range for the MAX4394ESD+?
The MAX4394ESD+ operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. This range supports standard 5V video rails and accommodates legacy ±5V systems. The device maintains full AC performance-including 85MHz bandwidth and 0.015% differential gain-across the entire specified voltage range. Absolute maximum supply is ±6V or 12V single-ended.
Does the MAX4394ESD+ require external compensation for unity-gain stability?
No, the MAX4394ESD+ is internally compensated for unity-gain stability. It does not require external compensation components. When configured in unity-gain mode, adding a 24Ω resistor in series with the feedback path optimizes AC performance by reducing peaking caused by parasitic LC resonance. This value is validated in the datasheet's "Choosing Resistor Values" section and applies directly to the MAX4394ESD+ in SO-14 package.
How does the disable function work on the MAX4394ESD+ and what is its impact on output impedance?
The MAX4394ESD+ features three independent disable pins (pins 1, 8, and 13) that place each amplifier into high-impedance state when pulled low. In disabled mode, output resistance rises to ≥40kΩ (typ. 95kΩ), and quiescent current drops to 450μA per channel. This allows safe insertion into video multiplexer paths without loading active channels. The 2pF output capacitance remains unchanged, preserving RF isolation performance.
Can the MAX4394ESD+ drive a 75Ω coaxial cable directly without external termination?
Yes, the MAX4394ESD+ is explicitly characterized to drive 75Ω loads and is widely deployed in video line driver applications. Its output stage delivers ±50mA into 75Ω with rail-to-rail swing and maintains 0.015% differential gain error. For optimal return loss and impedance matching, a series 75Ω resistor at the output (source termination) is recommended per standard video design practice-no additional buffer or transformer is needed.
What is the thermal performance of the MAX4394ESD+ in its SO-14 package?
The MAX4394ESD+ in 14-pin SO package has a junction-to-ambient thermal resistance (θJA) of 120°C/W on a single-layer board and 84°C/W on a multilayer board. At maximum rated ambient temperature (+85°C) and full 5.5mA per amplifier (16.5mA total), power dissipation is ~82.5mW-resulting in a junction temperature rise of ≤10°C above ambient on a multilayer board. This confirms robust thermal margin for continuous video line driver operation.
