Product details
Overview
MAX4394EUD from Maxim Integrated is a triple, rail-to-rail output, unity-gain stable voltage-feedback op amp with disable functionality, 85MHz -3dB bandwidth (dual-supply), 500V/µs slew rate, and 0.015% differential gain error. It operates from ±2.25V to ±5.5V or single 4.5V–11V supplies and targets high-fidelity video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4394EUD datasheet, MAX4394EUD pinout, MAX4394EUD application, or MAX4394EUD equivalent, this page delivers verified electrical specs, TSSOP-14 package layout, disable timing (40ns ON / 80ns OFF), channel isolation (-97dB), and real-world video interface design guidance - all confirmed for the exact MAX4394EUD ordering variant.
Technical Context
The MAX4394EUD implements a BiCMOS voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining unity-gain stability. Its input stage supports common-mode voltage down to VEE and within 2.25V of VCC, enabling robust operation in single-supply video signal chains.
Each of its three amplifiers features independent disable control (DISABLEA, DISABLEB, DISABLEC), rail-to-rail output swing (e.g., 0.75V to 1.6V on ±5V with 75Ω load), and low distortion (-59dBc SFDR at 5MHz), making it suitable for multi-channel analog video buffering and multiplexing where channel crosstalk and timing skew must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 85MHz (dual-supply); enables NTSC/PAL video signal amplification without attenuation in baseband. |
| Slew Rate | 500V/µs; supports clean 2VP-P large-signal transient response with 21ns settling to 0.1%. |
| Differential Gain/Phase | 0.015%/0.015° (NTSC, RL = 150Ω); preserves color fidelity in composite video transmission. |
| Disable Current | 0.45mA per amplifier (typ); reduces total quiescent draw to <1.4mA when all channels disabled. |
| Channel Isolation | -97dB (DC); prevents crosstalk between adjacent video channels in multi-amplifier routing. |
| Output Drive | ±50mA (sourcing/sinking into 75Ω); directly drives standard video termination without external buffers. |
| Supply Range | Single 4.5V–11V or dual ±2.25V–±5.5V; compatible with legacy 5V and modern low-voltage industrial rails. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DISABLEA | Active-high shutdown control for Amplifier A; logic-low (≤VCC – 3V) disables output to high-Z. |
| 2 | OUTC | Amplifier C output; rail-to-rail swing capable of ±50mA into 75Ω load. |
| 3 | INC- | Inverting input of Amplifier C; differential pair node with 1pF input capacitance. |
| 4 | INC+ | Noninverting input of Amplifier C; accepts common-mode down to VEE (–5V) in dual-supply mode. |
| 5 | VEE | Negative power supply rail; requires local 0.1µF bypass capacitor to ground. |
| 6 | INA+ | Noninverting input of Amplifier A; matched to INA- for <1mV offset voltage matching across channels. |
| 7 | INA- | Inverting input of Amplifier A; high-impedance node (3MΩ common-mode resistance). |
| 8 | OUTA | Amplifier A output; identical AC performance to OUTB/OUTC (85MHz BW, 500V/µs SR). |
| 9 | DISABLEC | Active-high shutdown for Amplifier C; independent timing (40ns enable, 80ns disable). |
| 10 | N.C. | No internal connection; must remain unconnected per datasheet. |
| 11 | N.C. | No internal connection; floating pin; avoid routing signals nearby. |
| 12 | DISABLEB | Active-high shutdown for Amplifier B; enables selective channel power gating. |
| 13 | INB- | Inverting input of Amplifier B; shares same input bias current spec (5–15µA) as other channels. |
| 14 | VCC | Positive power supply rail; requires local 0.1µF ceramic bypass capacitor. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6733MA/NOPB | Single-channel, no disable; higher 1.3GHz GBW but higher 15mA supply current per amp. | Lacks multi-channel integration and power-gating; requires three separate packages for triple function. | Select when ultra-wide bandwidth (>500MHz) is required and board space allows discrete placement. |
| THS3203D | Dual-channel only; no third amplifier or DISABLEC pin; 375V/µs slew rate; 220MHz bandwidth. | Cannot replace all three channels of MAX4394EUD without adding a third op amp and logic. | Choose for dual-channel high-speed applications where third channel is handled separately. |
Compared with LMH6733MA/NOPB and THS3203D, the MAX4394EUD uniquely integrates three matched, disable-capable amplifiers in one TSSOP-14 package-reducing PCB area by >40%, eliminating inter-channel skew, and enabling synchronized power management for video system standby modes.

FAQ
What supply voltages does the MAX4394EUD support?
The MAX4394EUD operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. In dual-supply mode, it delivers 85MHz bandwidth and 0.015% differential gain error. The device guarantees rail-to-rail output swing and input common-mode range extending to VEE, making it suitable for both legacy 5V and modern low-voltage video systems. All specifications in the MAX4394EUD datasheet are validated across this full range.
Does the MAX4394EUD have independent disable control for each amplifier?
Yes, the MAX4394EUD provides three dedicated disable inputs: DISABLEA (Pin 1), DISABLEB (Pin 12), and DISABLEC (Pin 9). Each controls its respective amplifier independently. When pulled low, the corresponding output enters high-impedance state with only 0.45mA quiescent current per disabled channel. This feature enables dynamic power management in multi-channel video routing - a capability not found in most triple op amps. The MAX4394EUD disable timing is specified at 40ns ON and 80ns OFF.
What is the output drive capability of the MAX4394EUD into 75Ω loads?
The MAX4394EUD delivers ±50mA output current into 75Ω loads under dual ±5V supply conditions, supporting full 2VP-P video swing with minimal droop. Its output voltage swing reaches 0.75V above VEE and 1.6V below VCC - sufficient for broadcast-compliant CVBS driving without external level-shifting. The device maintains <0.015% differential gain error and -59dBc SFDR at 5MHz under these conditions, confirming its suitability for professional video applications. This drive strength is consistent across all three amplifiers in the MAX4394EUD.
Can the MAX4394EUD be used in single-supply video applications?
Yes, the MAX4394EUD is fully specified for single-supply operation from 4.5V to 11V. Its input common-mode range extends to the negative rail (ground), and outputs swing rail-to-rail - enabling direct interfacing with ADCs and video DACs in 5V or 3.3V systems. While its -3dB bandwidth drops to 72MHz (small-signal) in single 5V mode, it retains 27MHz 0.1dB gain flatness and 0.015% differential gain error - meeting SDTV requirements. The MAX4394EUD's disable function remains fully operational, drawing only 0.3mA per disabled amplifier.
What package type is used for the MAX4394EUD and what are its key mechanical features?
The MAX4394EUD uses a 14-pin TSSOP package (package code U14-1, document 21-0066), measuring 5.0mm × 6.4mm × 1.2mm with 0.65mm pin pitch. It includes an exposed thermal pad for improved heat dissipation - critical for sustained 50mA output drive. The package is RoHS-compliant (lead-free) and rated for -40°C to +85°C operation. Unlike µMAX or SO variants, the TSSOP version offers superior thermal performance and board-level reliability for high-density video PCB layouts. This exact package is confirmed for the MAX4394EUD/V+T ordering variant.
