Product details
Overview
MAX4392EUA-T from Maxim Integrated is a dual, rail-to-rail output, unity-gain stable voltage-feedback op amp with disable functionality, 85MHz -3dB bandwidth (dual ±5V), 500V/µs slew rate, and 0.015% differential gain error. It operates from ±2.25V to ±5.5V supplies and targets high-fidelity video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4392EUA-T datasheet, MAX4392EUA-T pinout, MAX4392EUA-T application, or MAX4392EUA-T equivalent, key selection criteria include its dual-channel architecture with independent disable control, low-distortion video performance at 5MHz, rail-to-rail output swing into 75Ω loads, and µMAX-8 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4392EUA-T employs BiCMOS process technology to combine voltage-feedback stability with current-feedback speed characteristics. Its input stage accepts common-mode voltages down to VEE and within 2.25V of VCC, enabling single-supply operation with ground-referenced inputs.
Each amplifier features independent DISABLE pins (pins 1 and 5) that place outputs in high-impedance state (95kΩ) while drawing only 450µA per channel. The device achieves 21ns settling time to 0.1% and maintains 24MHz 0.1dB large-signal gain flatness for NTSC/PAL video fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 85MHz (dual ±5V supply, small-signal); enables full HD video signal amplification without attenuation |
| Slew Rate | 500V/µs; supports fast transient response for composite video pulses and digital video edges |
| Differential Gain/Phase Error | 0.015%/0.015° (NTSC, RL = 150Ω); meets broadcast-grade video color fidelity requirements |
| Output Drive Capability | ±50mA (RL = 75Ω); directly drives standard video coaxial loads without external buffers |
| Disable Current per Channel | 450µA; reduces system power by >90% when channel is inactive in multiplexed video routing |
| Input Voltage Noise Density | 13nV/√Hz @ 10kHz; preserves SNR in analog front-end signal chains before ADC sampling |
| Channel-to-Channel Isolation | -97dB @ DC; prevents crosstalk between dual video channels in multi-camera systems |
Pinout & Package
The MAX4392EUA-T is housed in an 8-pin µMAX package (package code U8-1), measuring 3mm × 3mm × 1.1mm with exposed pad for thermal enhancement. Pin 1 is top-marked with laser-etched identifier; recommended PCB land pattern follows Maxim document 21-0036.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DISABLEA | Active-high shutdown control for Amplifier A; tie to VCC to enable, GND to disable |
| 2 | INA− | Inverting input for Amplifier A; matched impedance critical for video differential signaling |
| 3 | INA+ | Noninverting input for Amplifier A; accepts common-mode down to VEE (−5V) |
| 4 | VEE | Negative supply rail; requires 0.1µF ceramic bypass capacitor placed adjacent to pin |
| 5 | DISABLEB | Active-high shutdown control for Amplifier B; independent of DISABLEA for flexible channel gating |
| 6 | INB− | Inverting input for Amplifier B; electrically isolated from Amplifier A inputs per datasheet CHISO spec |
| 7 | INB+ | Noninverting input for Amplifier B; supports DC-coupled video input with rail-to-rail common-mode range |
| 8 | VCC | Positive supply rail; requires 0.1µF ceramic bypass capacitor; supports 4.5V–11V single or ±2.25V–±5.5V dual operation |
Key Features
| Feature | Design Value |
|---|---|

| Independent per-channel disable | Enables selective power-down of one amplifier in dual-video-path systems without affecting the other channel's operation |
| Low distortion at 5MHz | −59dBc SFDR ensures minimal harmonic contamination in digitized video signals prior to ADC conversion |
| High channel isolation | −97dB DC isolation prevents interference between co-located video channels in compact surveillance enclosures |
| Optimized for video line driving | 24MHz 0.1dB large-signal gain flatness and 21ns 0.1% settling meet SMPTE 259M timing and fidelity requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MA/NOPB | Single-channel, no disable function; higher 1.7GHz GBW but 12mA quiescent current vs. 11mA for MAX4392 | Lacks per-channel shutdown; unsuitable for power-gated multi-channel video routing | Select when maximum bandwidth (>500MHz) is required and disable capability is unnecessary |
| THS3202D | Dual-channel with disable, but 1.8GHz GBW and 15mA supply current; requires ±5V only, no single-supply operation | Higher power consumption and narrower supply range limit use in battery-powered or 5V-only systems | Prefer for ultra-high-speed test equipment where 21ns settling is insufficient |
Compared with LMH6702MA/NOPB and THS3202D, the MAX4392EUA-T delivers optimal balance of video-optimized distortion performance, dual-channel independence, and low-power disable-making it uniquely suited for cost-sensitive, space-constrained, multi-channel analog video interfaces.

FAQ
What supply voltage ranges does the MAX4392EUA-T support?
The MAX4392EUA-T operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. This flexibility allows direct integration into both 5V embedded systems and ±5V professional video equipment. The input common-mode range extends to VEE (ground in single-supply mode), and output swings to within 200mV of each rail-ensuring full dynamic range utilization across all supported supply configurations. MAX4392EUA-T maintains specified AC performance across this entire voltage range.
Does the MAX4392EUA-T support rail-to-rail input operation?
No, the MAX4392EUA-T supports rail-to-rail *output* swing but not rail-to-rail input. Its input common-mode voltage range extends to the negative supply rail (VEE) and up to VCC − 2.25V. For example, with ±5V supplies, inputs operate from −5V to +2.75V. This design enables robust operation with ground-referenced video signals while maintaining excellent CMRR (70–90dB) across the usable range. MAX4392EUA-T's input stage is optimized for video fidelity-not universal rail-to-rail input coverage.
How does the disable function affect output impedance and leakage in the MAX4392EUA-T?
When disabled (DISABLEA or DISABLEB = logic low), the MAX4392EUA-T output enters high-impedance state with 40–95kΩ resistance and <2pF capacitance-verified per datasheet ROUT(OFF) and COUT specs. Leakage current remains below 100nA over temperature. This behavior enables clean signal multiplexing in video switch matrices without loading downstream stages. MAX4392EUA-T's disable timing (40ns ON, 80ns OFF) ensures glitch-free transitions during live video routing.
Can the MAX4392EUA-T drive 75Ω coaxial cables directly?
Yes, the MAX4392EUA-T is explicitly characterized to drive 75Ω loads with ±50mA output current and 0.015% differential gain error-meeting SMPTE 259M requirements for SD-SDI baseband video. Its 21ns 0.1% settling time and 24MHz 0.1dB large-signal gain flatness ensure minimal edge ringing and color fidelity. Layout best practices (microstrip traces, 0.1µF local bypassing) must be followed; MAX4392EUA-T's output stage is optimized for this load, unlike general-purpose op amps.
What is the thermal performance of the MAX4392EUA-T in µMAX-8 package?
The MAX4392EUA-T in µMAX-8 (3mm × 3mm) has a junction-to-ambient thermal resistance (θJA) of 125°C/W per Maxim's package documentation. At 11mA total quiescent current (5.5mA per amplifier) and 5V dual supply, power dissipation is ~60mW-resulting in <7.5°C junction rise above ambient. The exposed pad improves heat transfer; PCB copper area under the pad further reduces θJA. MAX4392EUA-T is rated for −40°C to +85°C operation with guaranteed performance across this range.
