Product details
Overview
MAX4393EUB+ from Analog Devices is a dual-channel, rail-to-rail output, unity-gain stable voltage-feedback op amp with disable functionality. It delivers 85MHz -3dB bandwidth, 500V/μs slew rate, and 0.015% differential gain error, optimized for high-fidelity video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4393EUB+ datasheet, MAX4393EUB+ pinout, MAX4393EUB+ application, or MAX4393EUB+ equivalent, key selection criteria include its dual-amplifier architecture with independent disable control per channel, 10-pin μMAX® package footprint, ±2.25V to ±5.5V dual-supply operation, and verified NTSC-compliant video performance at 75Ω loads.
Technical Context
The MAX4393EUB+ employs BiCMOS process technology to combine current-feedback speed advantages with voltage-feedback stability-enabling 85MHz bandwidth while maintaining unity-gain stability. Its input stage accepts common-mode voltages down to VEE (–5.5V) and up to VCC – 2.25V, supporting single- or dual-supply configurations without level-shifting circuitry.
Each amplifier features independent DISABLEA and DISABLEB inputs that place outputs in high-impedance state (ROUT(OFF) = 40–95kΩ) while drawing only 450μA total quiescent current. Channel-to-channel isolation exceeds –97dB at DC, minimizing crosstalk in multi-channel video routing applications.

| Supply Range | ±2.25V to ±5.5V - compatible with standard analog video supply rails |
| Channel Isolation | –97dB - prevents interference between adjacent video channels |
Pinout & Package
The MAX4393EUB+ is housed in a 10-pin μMAX® package (package code U10+2), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement. This RoHS-compliant, lead-free surface-mount package supports high-density PCB layouts and provides low thermal resistance (θJA = 180°C/W on single-layer board).

| 2 | INA– | Inverting input for Amplifier A - matched to INA+ for precision gain setting |
| 3 | INA+ | Noninverting input for Amplifier A - accepts VEE to (VCC – 2.25V) common-mode range |
| 4 | DISABLEA | Active-low enable for Amplifier A - logic threshold VIL = VCC – 3V, VIH = VCC – 1.25V |
| 5 | VEE | Negative supply rail - requires 0.1μF bypass capacitor to ground |
| 6 | VCC | Positive supply rail - requires 0.1μF bypass capacitor to ground |
| 7 | DISABLEB | Active-low enable for Amplifier B - independent control from DISABLEA |
| 8 | INB+ | Noninverting input for Amplifier B - electrically isolated from Amplifier A inputs |
| 9 | INB– | Inverting input for Amplifier B - matched pair with INB+ for balanced performance |
| 10 | OUTB | Amplifier B output - identical AC/DC specs to OUTA; no shared internal nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MA/NOPB | Single-channel, no disable function; higher 1.7GHz GBW but 10× higher quiescent current (12mA) | Lacks per-channel shutdown; unsuitable for power-gated multi-source video switches | Select when ultra-wide bandwidth (>500MHz) is required and power budget allows |
| THS3202DGN | Dual-channel with disable, but 1.8GHz GBW and 12mA per channel; requires external compensation | Not unity-gain stable; needs feedback network design for video gain configurations | Select for non-standard gain >2 applications where stability can be actively managed |
Compared with LMH6702MA/NOPB and THS3202DGN, the MAX4393EUB+ uniquely balances video-optimized distortion performance, integrated disable logic, unity-gain stability, and 5.5mA total quiescent current-making it the only drop-in solution for space-constrained, multi-channel, low-power analog video routing.

FAQ
What is the operating supply voltage range for the MAX4393EUB+?
The MAX4393EUB+ operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. At ±5V, it achieves full 85MHz bandwidth and 0.015% differential gain error. The input common-mode range extends to VEE and within 2.25V of VCC, enabling robust operation across its rated supply range without external level shifting. MAX4393EUB+ maintains specified AC performance across –40°C to +85°C ambient temperature.
Does the MAX4393EUB+ support rail-to-rail input operation?
No, the MAX4393EUB+ does not support rail-to-rail input operation. Its input common-mode voltage range extends to the negative supply rail (VEE) but only to VCC – 2.25V on the positive side. This design enables high CMRR (70–95dB) and low input offset voltage (5–28mV) while maintaining stability and video-grade distortion performance. MAX4393EUB+ is optimized for applications where the input signal remains within this defined range, such as post-processing video signals referenced to ground or negative rails.
How does the disable function work on the MAX4393EUB+?
The MAX4393EUB+ features two independent disable inputs: DISABLEA (Pin 4) and DISABLEB (Pin 7). Driving either pin low places the corresponding amplifier's output in high-impedance state (ROUT(OFF) = 40–95kΩ) while reducing total supply current to 450μA. Logic thresholds are VIL = VCC – 3V and VIH = VCC – 1.25V, ensuring compatibility with standard 3.3V or 5V logic. MAX4393EUB+ achieves 40ns turn-on and 80ns turn-off times, enabling fast channel switching in video multiplexer applications.
Can the MAX4393EUB+ drive a 75Ω video load directly?
Yes, the MAX4393EUB+ is explicitly characterized to drive 75Ω video loads. It delivers ±50mA output current and maintains 0.015% differential gain and 0.015° differential phase error into 150Ω loads (standard test condition), with verified performance into 75Ω. Output voltage swing is specified as 1.0V to 1.7V below rails under 75Ω load, sufficient for 1VP-P CVBS signals. MAX4393EUB+ includes internal compensation for unity-gain stability, eliminating need for external feedback components in basic line-driver configurations.
What package type is used for the MAX4393EUB+?
The MAX4393EUB+ uses a 10-pin μMAX® package (outline 21-0061, land pattern 90-0330), measuring 3mm × 3mm × 0.8mm with exposed thermal pad. This RoHS-compliant, lead-free surface-mount package offers low thermal resistance (θJA = 180°C/W on single-layer board) and is pin-compatible with other 10-pin μMAX devices in the MAX43xx family. MAX4393EUB+ requires standard reflow soldering profiles and supports automated optical inspection due to its gull-wing lead geometry.
