Product details
Overview
MAX4394ESD+T 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 MAX4394ESD+T datasheet, MAX4394ESD+T pinout, MAX4394ESD+T application, or MAX4394ESD+T equivalent, key selection criteria include channel count (3), disable capability per amplifier, 75Ω video load drive compliance, low distortion at 5MHz (-59dBc SFDR), and SO-14 package thermal performance (θJA = 120°C/W).
Technical Context
The MAX4394ESD+T employs BiCMOS process technology to combine current-feedback speed advantages with voltage-feedback stability-enabling 85MHz bandwidth and 500V/μs slew rate while maintaining unity-gain stability. Its input stage supports common-mode voltage down to VEE and up to VCC − 2.25V, enabling direct interface with single-supply video sources.
All three amplifiers feature independent disable pins (DISABLEA, DISABLEB, DISABLEC), each sinking only 450μA in disabled state while raising output impedance to 95kΩ. Output drive capability reaches ±50mA into 75Ω loads, with 21ns settling time to 0.1% and 0.015° differential phase error for NTSC-compliant video signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 85MHz - supports full HD video baseband signal transmission without attenuation |
| Slew Rate | 500V/μs - enables clean 2VP-P step response with minimal distortion |
| Differential Gain Error | 0.015% - meets broadcast-grade video fidelity requirements for NTSC/PAL |
| Supply Voltage Range | Single 4.5V–11V or dual ±2.25V–±5.5V - compatible with standard 5V and ±5V video system rails |
| Disable Current (per amp) | 450μA - reduces total quiescent power to <2.5mA when all channels disabled |
| Output Drive | ±50mA into 75Ω - directly drives coaxial video lines without external buffers |
| Settling Time (0.1%) | 21ns - ensures accurate pixel-level timing in high-speed video digitization |
Pinout & Package
MAX4394ESD+T is housed in a 14-pin SO (Small Outline) package with exposed pad thermal enhancement (θJA = 120°C/W, θJC = 37°C/W). Pin layout supports independent control of three amplifiers with dedicated disable inputs and shared power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 13 | OUTA / OUTB / OUTC | Amplifier A/B/C outputs - rail-to-rail swing capable; drive 75Ω video loads directly |
| 2, 9, 12 | INA− / INB− / INC− | Inverting inputs - support differential video signaling and feedback configurations |
| 3, 10, 11 | INA+ / INB+ / INC+ | Noninverting inputs - accept DC-coupled or AC-coupled video signals down to VEE |
| 4 | VEE | Negative supply - connects to ground (single-supply) or −5V (dual-supply); bypass with 0.1μF |
| 5, 6, 7 | DISABLEA / DISABLEB / DISABLEC | Active-low disable controls - logic low (≤VCC − 3V) places corresponding output in high-Z state |
| 14 | VCC | Positive supply - accepts 4.5V–11V; requires local 0.1μF ceramic bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Within 200mV of VCC/VEE - preserves dynamic range across full video signal amplitude |
| Independent per-channel disable | Three separate DISABLE pins enable selective power gating in multi-channel video routing |
| Low differential gain/phase error | 0.015%/0.015° - eliminates color shift and timing jitter in analog video transmission |
| High output current drive | ±50mA into 75Ω - eliminates need for external line drivers in CCTV and STB designs |
| Unity-gain stable architecture | No external compensation required - simplifies PCB layout for video gain stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4392ESA+T | Dual-channel, no disable function; SO-8 package; same 85MHz BW and 0.015% DG/Dφ | Lacks per-channel shutdown; unsuitable for power-gated multi-output systems | Select when only two video paths are needed and disable is unnecessary |
| THS3201D | Single-channel, current-feedback architecture; 375MHz BW; no rail-to-rail output; no disable | Higher bandwidth but higher power (12.5mA/ch); requires level-shifting for single-supply video | Choose for ultra-wideband RF/video hybrid signals where speed outweighs power and integration |
Compared with MAX4392ESA+T and THS3201D, the MAX4394ESD+T uniquely delivers triple-channel integration with per-amplifier disable in a thermally robust SO-14 package-enabling compact, low-power, multi-output video routing without sacrificing broadcast-grade signal fidelity.

FAQ
What is the operating temperature range for MAX4394ESD+T?
The MAX4394ESD+T is specified for operation from −40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in enclosed surveillance enclosures and set-top box chassis where internal temperatures exceed commercial limits. The SO-14 package's θJA of 120°C/W allows thermal design margin under continuous 5V/±5V operation with proper PCB copper pour.
Does MAX4394ESD+T support single-supply operation?
Yes, MAX4394ESD+T supports true single-supply operation from 4.5V to 11V. Its input common-mode range extends to VEE (ground), and outputs swing rail-to-rail-enabling direct interface with 0V-referenced video DACs and ADCs. For optimal NTSC performance, Analog Devices recommends VCC = 5V and VEE = 0V with 0.1μF bypass capacitors on both supply pins.
How does the disable function work on MAX4394ESD+T?
Each amplifier in MAX4394ESD+T has a dedicated active-low disable pin (DISABLEA, DISABLEB, DISABLEC). Pulling any DISABLE pin ≤(VCC − 3V) places that amplifier's output in high-impedance state (ROUT(OFF) = 40–95kΩ) while reducing its quiescent current to 450μA. This enables independent power gating-critical for dynamic video path selection in multi-output systems without affecting other active channels.
Can MAX4394ESD+T drive 75Ω coaxial cables directly?
Yes, MAX4394ESD+T is explicitly characterized to drive 75Ω loads with ±50mA output current and maintains 0.015% differential gain error-meeting broadcast video standards. When driving long cables, Analog Devices recommends adding a 24Ω series resistor in the feedback path (per amplifier) to optimize AC response and minimize peaking caused by cable capacitance.
What is the small-signal bandwidth of MAX4394ESD+T at 100mVP-P output?
The small-signal −3dB bandwidth of MAX4394ESD+T is 85MHz at 100mVP-P output amplitude. This specification ensures flat frequency response across the entire baseband video spectrum (DC to ~5.5MHz for NTSC), with measured 0.1dB gain flatness extending to 27MHz-providing ample margin for harmonics and edge sharpness in high-resolution analog video signals.
