Product details
Overview
The MAX4380EXT from Maxim Integrated is a single, unity-gain-stable, rail-to-rail output operational amplifier with integrated disable functionality, designed for high-speed video and RF signal conditioning. It delivers 210MHz -3dB bandwidth, 485V/µs slew rate, and 55MHz 0.1dB gain flatness while operating from a +4.5V to +11V single supply. Its ultra-small SC70-6 package and high-impedance disable mode make it ideal for space-constrained video line drivers and battery-powered instrumentation.
For engineers reviewing the MAX4380EXT datasheet, MAX4380EXT pinout, MAX4380EXT application, or MAX4380EXT equivalent, key selection criteria include its 210MHz bandwidth at unity gain, rail-to-rail output swing within 50mV of rails (with 2kΩ load), low 0.02%/0.08° differential gain/phase error for NTSC video, 16ns settling time to 0.1%, and SC70-6 thermal performance (245mW at +70°C).
Technical Context
The MAX4380EXT employs voltage-feedback architecture enhanced with current-feedback techniques to achieve both wide bandwidth and fast slew rate. Its input stage supports common-mode voltages extending 200mV below VEE and up to 2.25V below VCC, enabling ground-sensing operation in single-supply systems.
It features an active-high DISABLE pin that places the output in a high-impedance state (27–35kΩ) with only 0.45–0.6mA quiescent current in disabled mode. The device is internally compensated for stable unity-gain operation and optimized for driving 75Ω video loads with minimal distortion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Higher 1.7GHz GBW but no disable function; 12.5mA supply current vs. 5.5mA | Lacks integrated disable-requires external MOSFET switch for power gating | Choose when >1GHz bandwidth is required and disable is implemented externally |
| ADA4817-1ARMZ | Faster 1.05GHz GBW, lower 4nV/√Hz noise, but dual-supply only (±2.5V to ±5V) | Not suitable for single +5V systems; requires bipolar supply generation | Prefer for precision low-noise applications where dual supply is available and disable is unnecessary |
Compared with LMH6702MF/NOPB and ADA4817-1ARMZ, the MAX4380EXT uniquely combines 210MHz bandwidth, rail-to-rail output, active-high disable, and single-supply operation in a 6-pin SC70 package-making it optimal for space- and power-constrained video routing and portable instrumentation.

FAQ
What is the operating supply voltage range for the MAX4380EXT?
The MAX4380EXT operates from a single +4.5V to +11V supply or dual ±2.25V to ±5.5V supplies. For single-supply use, VEE is connected to ground. Its PSRR is guaranteed across this full range, and internal circuitry remains functional down to +4.5V, making the MAX4380EXT suitable for battery-powered systems with varying voltage profiles.
Does the MAX4380EXT support rail-to-rail input common-mode voltage?
The MAX4380EXT supports rail-to-rail *output*, but its input common-mode range extends from (VEE − 0.2V) to (VCC − 2.25V). In +5V single-supply operation, this means the input can go 200mV below ground and up to +2.75V-enabling true ground-sensing capability while maintaining excellent CMRR (>70dB) across the usable range.
How does the DISABLE pin function on the MAX4380EXT?
The DISABLE pin on the MAX4380EXT is active-high: when pulled to VCC, the amplifier operates normally; when driven low (≤VCC − 3V), the output enters a high-impedance state (27–35kΩ) and quiescent current drops to ≤0.6mA. Enable/disable transition times are 100ns and 1µs respectively, supporting fast video multiplexing without visible glitches in the MAX4380EXT signal path.
What is the typical differential gain and phase error of the MAX4380EXT?
The MAX4380EXT achieves 0.02% differential gain error and 0.08° differential phase error under NTSC conditions with a 150Ω load-meeting broadcast-quality video specifications. These values are measured at room temperature and remain stable across the −40°C to +85°C operating range, ensuring consistent color fidelity in surveillance and set-top box applications using the MAX4380EXT.
Can the MAX4380EXT drive a 75Ω video load directly?
Yes-the MAX4380EXT is explicitly characterized for 75Ω video line driving, delivering 25–50mA output current into 75Ω loads. Its output voltage swing remains within specification (VOL − VEE ≤ 0.125V, VCC − VOH ≤ 1.7V) and maintains 0.02%/0.08° differential gain/phase accuracy. Layout best practices (e.g., microstrip traces, no 90° bends) are recommended to preserve signal integrity at full bandwidth.
