Product details
Overview
MAX4393EUB+T from Analog Devices is a dual-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 MAX4393EUB+T datasheet, MAX4393EUB+T pinout, MAX4393EUB+T application, or MAX4393EUB+T equivalent, key selection criteria include its dual-amplifier architecture with per-channel disable, 10-pin μMAX package footprint, 27MHz 0.1dB gain flatness for NTSC/PAL video, and guaranteed operation across –40°C to +85°C.
Technical Context
The MAX4393EUB+T employs BiCMOS process technology to combine voltage-feedback stability with current-feedback speed characteristics, enabling 500V/μs slew rate while maintaining unity-gain stability. Its input stage supports common-mode voltage down to VEE (ground in single-supply), and its output stage delivers rail-to-rail swing with ±50mA drive capability into 75Ω loads.
Each amplifier features independent DISABLE pins (pins 1 and 10) that place the output in high-impedance state (≥40kΩ) while reducing quiescent current to 450μA per channel. Channel-to-channel isolation exceeds –97dB at DC, ensuring minimal crosstalk in multi-channel video routing applications.

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 |
|---|---|---|---|
| THS3202DGNR | Higher 1.8GHz bandwidth but no disable function; 14-pin MSOP vs. 10-pin μMAX | Not suitable for power-gated video routing; better for RF signal chain stages | Select only if disable is unnecessary and bandwidth >100MHz required |
| LMH6702MA/NOPB | Single-channel, no disable; 8-pin SOIC; 1.8GHz bandwidth, higher 12mA quiescent current | Requires two devices for dual-channel use; lacks per-channel shutdown | Choose when cost-per-channel is prioritized over integration and power control |
Compared with THS3202DGNR and LMH6702MA/NOPB, the MAX4393EUB+T uniquely integrates dual amplifiers, independent disable, and broadcast-grade video fidelity in a compact 10-pin μMAX package-enabling lower BOM count, reduced PCB area, and dynamic power management in space- and power-sensitive video systems.

FAQ
What is the maximum capacitive load the MAX4393EUB+T can drive without oscillation?
The MAX4393EUB+T is not optimized for direct capacitive loading. Driving >15pF requires an isolation resistor (typically 10Ω–15Ω) in series with the output to maintain stability. Figure 2 in the datasheet shows this configuration, and Figure 3 provides optimal RISO values up to 500pF. Without isolation, even 33pF causes peaking; with 15Ω, performance remains flat up to 180pF.
Does the MAX4393EUB+T support single-supply operation with ground-referenced inputs?
Yes. The MAX4393EUB+T's input common-mode range extends to VEE (ground in single-supply mode), allowing true ground-referenced signal handling. With VCC = 5V and VEE = 0V, inputs operate from 0V to 2.75V, and outputs swing within 200mV of both rails-making it ideal for 0V–5V video systems like CVBS drivers.
How does the disable function affect output impedance and settling behavior?
When DISABLEA or DISABLEB is pulled low, the corresponding output enters high-impedance state with ≥40kΩ resistance and <2pF capacitance. Disable ON/OFF times are 40ns and 80ns respectively-fast enough for frame-synchronized video blanking. During disable, output voltage floats; external pull-downs may be needed for defined DC state.
Can the MAX4393EUB+T drive a 75Ω coaxial cable directly?
Yes. The MAX4393EUB+T delivers ±50mA into 75Ω loads, supporting standard video line driving without external buffers. At 5V supply, it swings >4VPP into 75Ω with <0.015% differential gain error-meeting SMPTE 253M and ITU-R BT.601 video fidelity requirements for broadcast and professional applications.
What is the thermal performance of the MAX4393EUB+T in its 10-pin μMAX package?
The MAX4393EUB+T in 10-pin μMAX (U10+2) has θJA = 180°C/W on single-layer board and 113.1°C/W on multilayer board. At 10mA total quiescent current (5mA per amp) and 5V supply, power dissipation is ~50mW-resulting in <9°C junction rise above ambient in typical layouts. The exposed pad improves thermal conduction when soldered to copper.
