Product details
Overview
MAX4383EUD+T from Maxim Integrated is a quad-channel, rail-to-rail output, unity-gain-stable voltage-feedback op amp optimized for high-speed video and RF signal routing. It delivers 210MHz -3dB bandwidth, 485V/µs slew rate, and 0.02%/0.08° differential gain/phase error in a 14-pin TSSOP package, enabling precision video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4383EUD+T datasheet, MAX4383EUD+T pinout, MAX4383EUD+T application, or MAX4383EUD+T equivalent, this page provides verified pin functions, real-world video interface use cases, confirmed AC/DC specifications, disable-mode timing (1µs disable time), and two validated alternative parts with documented functional trade-offs.
Technical Context
The MAX4383EUD+T integrates four independent amplifiers sharing a common disable control architecture, each featuring current-feedback-enhanced voltage-feedback topology to achieve 210MHz bandwidth and 485V/µs slew rate while maintaining DC precision. Its input common-mode range extends 200mV below VEE and to within 2.25V of VCC, supporting ground-sensing operation in +5V single-supply systems.
Each amplifier includes a dedicated DISABLE pin (DISABLEA–DISABLED) that places its output in high-impedance state (27–35kΩ) with 2pF output capacitance, enabling clean multiplexing in video switch matrices. The device operates from +4.5V to +11V single supply or ±2.25V to ±5.5V dual supplies, with quiescent current of 7.5–10mA per amplifier when enabled.

Use Scenario: Portable oscilloscope front-end amplifying sensor signals before digitization under tight power budgets. IC Role / Device Role / Timing Role: Low-power, high-bandwidth buffer isolating ADC input from source impedance variations. Use Value: 7.5mA per amplifier enables four-channel acquisition at <30mA total; 16ns settling ensures accurate sampling of fast transients. |
Use Scenario: Driving SAR or pipeline ADC inputs requiring wide bandwidth, low distortion, and precise DC offset control. IC Role / Device Role / Timing Role: Precision driver conditioning video or communication signals prior to digitization. Use Value: −65dBc SFDR at 5MHz preserves ENOB; input common-mode range beyond ground allows DC-coupled sensor interfacing. |
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 |
|---|---|---|---|
| MAX4382EUD+ | Quad-channel, identical 210MHz bandwidth and 485V/µs slew rate, but in 14-pin SO package (wider 3.9mm body vs. TSSOP's 4.4mm × 5mm). | SO package offers higher thermal mass and easier hand-soldering; TSSOP preferred for space-constrained PCBs. | Select MAX4382EUD+ when board assembly favors SO footprint or thermal dissipation is critical; MAX4383EUD+T for density-optimized layouts. |
| THS4271DR | Single-channel, 1.3GHz bandwidth, 3000V/µs slew rate, but no disable function and higher 18mA supply current per channel. | Higher speed suits RF IF stages; lack of disable limits multiplexing use; not pin-compatible. | Choose THS4271DR only for ultra-wideband (>500MHz) applications where disable is unnecessary and power is secondary. |
Compared with MAX4382EUD+ and THS4271DR, the MAX4383EUD+T uniquely combines quad-channel integration, per-amplifier disable, and 75Ω video-optimized drive in a compact TSSOP-making it optimal for multi-output video routing where space, power, and switching integrity are jointly constrained.

FAQ
What is the operating supply voltage range for the MAX4383EUD+T?
The MAX4383EUD+T operates from a single +4.5V to +11V supply or dual ±2.25V to ±5.5V supplies. At +5V single supply, it achieves full 210MHz bandwidth and rail-to-rail output swing while consuming 7.5mA per amplifier. The device guarantees functionality across the full −40°C to +85°C temperature range under these conditions, with PSRR of 50–62dB.
Does the MAX4383EUD+T support rail-to-rail input operation?
No, the MAX4383EUD+T does not support rail-to-rail input. Its input common-mode voltage range extends 200mV below VEE (to −0.2V on +5V supply) and to within 2.25V of VCC (to +2.75V on +5V supply). This "beyond-the-rail" negative range enables true ground-referenced input in single-supply systems, but the upper limit excludes full VCC-referenced signals without level shifting.
How does the disable function work on the MAX4383EUD+T?
Each amplifier in the MAX4383EUD+T has its own active-low DISABLE pin (DISABLEA–DISABLED). Pulling a DISABLE pin to GND places that amplifier's output in high-impedance state (27–35kΩ) with only 2pF capacitance, enabling clean multiplexing. Enable time is 100ns; disable time is 1µs. All amplifiers remain powered-only output stages are disabled-so quiescent current drops to 0.45–0.6mA per disabled channel.
Can the MAX4383EUD+T drive a 75Ω video load directly?
Yes, the MAX4383EUD+T is explicitly characterized for 75Ω loads. With +5V supply and RL = 75Ω to ground, it delivers VCC–VOH ≤ 1.7V and VOL–VEE ≤ 0.5V, yielding >4.3Vp-p output swing. It sources/sinks up to 75mA per channel and maintains −65dBc SFDR at 5MHz, meeting SMPTE/NTSC video line driver requirements without external components.
What is the small-signal bandwidth of the MAX4383EUD+T at unity gain?
The MAX4383EUD+T has a small-signal −3dB bandwidth of 210MHz at unity gain (AVCL = +1V/V) with VOUT = 100mVp-p, as specified in the AC Electrical Characteristics table. This bandwidth is maintained across the full −40°C to +85°C operating temperature range and is internally compensated for stability at unity gain, eliminating need for external compensation networks.
