Product details
Overview
MAX4389EUT+T from Analog Devices is a single-channel, rail-to-rail output, high-speed voltage-feedback op amp with disable functionality, designed for video line driving and analog signal conditioning. It delivers 85MHz -3dB bandwidth, 500V/μs slew rate, and 0.015% differential gain error at NTSC, operating from 4.5V to 11V single supply or ±2.25V to ±5.5V dual supply.
For engineers reviewing the MAX4389EUT+T datasheet, MAX4389EUT+T pinout, MAX4389EUT+T application, or MAX4389EUT+T equivalent, key selection criteria include its 6-pin SOT23 package, 40ns enable/disable timing, 75Ω video load drive capability, low 5.5mA quiescent current, and verified performance in surveillance video systems and ADC interface circuits.
Technical Context
The MAX4389EUT+T employs BiCMOS process technology and combines voltage-feedback architecture 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 (ground in single-supply), and its output stage delivers rail-to-rail swing with ±50mA drive into 75Ω loads.
Disable mode actively isolates the output with 95kΩ impedance and reduces supply current to 450μA, enabling use in multiplexer/switch configurations. The device exhibits 21ns settling time to 0.1%, 27MHz 0.1dB gain flatness, and -59dBc SFDR at 5MHz - all confirmed under standard test conditions (VCC = 5V, TA = +25°C, RL = 75Ω).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4389EXT+T | Identical electrical specs but packaged in 6-pin SC70 (smaller footprint, higher θJA = 326°C/W) | Better suited for ultra-dense layouts where board area is more critical than thermal margin | Select when PCB real estate is constrained and thermal derating can be accommodated |
| LMH6702MF/NOPB | Higher 1.7GHz GBW, no disable function, 5-pin SOT23, 12.5mA IQ | Targeted at RF/IF signal chains rather than video line driving; lacks rail-to-rail output and video-optimized distortion specs | Choose only for non-video, wideband amplifier needs where disable and low distortion are not required |
Compared with MAX4389EXT+T, the MAX4389EUT+T offers superior thermal dissipation (θJA = 115°C/W vs. 326°C/W) in the same pin count, while LMH6702MF/NOPB trades video-specific fidelity for raw bandwidth-making MAX4389EUT+T the optimal choice for cost-sensitive, thermally constrained video line drivers requiring disable control.

FAQ
What is the maximum capacitive load the MAX4389EUT+T can drive without instability?
The MAX4389EUT+T is not optimized for direct capacitive loading. Driving >15pF without isolation causes peaking and potential oscillation. For loads >15pF, a series isolation resistor (10–27Ω) must be placed between the MAX4389EUT+T output and the capacitive load. This configuration maintains stability and preserves 0.1dB gain flatness up to 27MHz, as validated in the device's typical operating characteristics.
Does the MAX4389EUT+T support dual-supply operation, and what are the valid voltage ranges?
Yes, the MAX4389EUT+T supports dual-supply operation from ±2.25V to ±5.5V. Valid supply combinations include ±2.25V, ±3V, ±4V, and ±5V. Operation outside this range violates absolute maximum ratings and may cause permanent damage. The device maintains specified AC performance (e.g., 85MHz bandwidth, 500V/μs slew rate) across the full dual-supply range at TA = +25°C.
What is the input common-mode voltage range for the MAX4389EUT+T in single-supply mode?
In single-supply mode (e.g., VCC = 5V, VEE = 0V), the MAX4389EUT+T input common-mode voltage range extends from VEE (0V) to VCC − 2.25V (2.75V). This allows direct interfacing with ground-referenced sensors or DAC outputs without level-shifting circuitry, while maintaining guaranteed CMRR ≥70dB across the specified range.
How does the disable function affect output impedance and leakage in the MAX4389EUT+T?
When the DISABLE pin is pulled low (≤ VCC − 3V), the MAX4389EUT+T output enters high-impedance state with ROUT(OFF) = 40–95kΩ and output capacitance ≤2pF. Output leakage remains <100nA over temperature (−40°C to +85°C), ensuring minimal signal coupling in multiplexed video architectures. This behavior is fully characterized and production-tested per the datasheet's DC electrical specifications.
Can the MAX4389EUT+T be used in a unity-gain inverting configuration, and what resistor values are recommended?
Yes, the MAX4389EUT+T is unity-gain stable in both inverting and noninverting configurations. For optimal AC performance in unity-gain inverting mode, use RF = RG = 24Ω. Larger resistors degrade bandwidth due to interaction with 1pF input capacitance; for example, 2kΩ resistors create a 79.6MHz pole within the amplifier's 85MHz bandwidth, risking instability. Surface-mount 24Ω resistors minimize parasitics and preserve full small-signal response.
