Product details
Overview
The MAX4380EXT+T from Maxim Integrated is a single, rail-to-rail output, high-speed voltage-feedback operational amplifier with integrated disable functionality. 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, 6.5mA quiescent current per amplifier, and high-impedance disable mode make it ideal for battery-powered video line drivers and analog-to-digital converter interfaces.
For engineers reviewing the MAX4380EXT+T datasheet, MAX4380EXT+T pinout, MAX4380EXT+T application, or MAX4380EXT+T equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed video and instrumentation use cases, and two rigorously cross-checked alternative op amps - all grounded in the official MAX4380–MAX4384 family datasheet Rev 2 (4/03).
Technical Context
The MAX4380EXT+T employs current-feedback techniques within a voltage-feedback architecture to achieve both unity-gain stability and wideband performance. Its input stage supports common-mode voltages extending 200mV below VEE (ground in single-supply operation) and up to 2.25V below VCC, enabling true ground-sensing capability.
It features an active disable function that places the output in a high-impedance state (27kΩ–35kΩ) with only 0.45–0.6mA quiescent current, making it suitable for multiplexed video routing. Output swing reaches within 50mV of both rails under 2kΩ load, and distortion remains low (–63dBc THD, –65dBc SFDR at 5MHz) for precision video signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 210MHz - enables full HD video signal amplification without attenuation at baseband frequencies. |
| Slew Rate | 485V/µs - supports fast transient response for composite video and digital video signals with sharp edges. |
| Supply Range | +4.5V to +11V single supply - compatible with standard 5V and 9V systems without dual-rail generation. |
| Input Common-Mode Range | VEE − 0.2V to VCC − 2.25V - allows direct interface to ground-referenced sensors and ADC inputs. |
| Output Voltage Swing | Within 50mV of rails (RL = 2kΩ) - maximizes dynamic range in single-supply video applications. |
| Disable Current | 0.45–0.6mA - reduces power by >90% vs active mode (5.5mA), critical for portable instrumentation duty cycling. |
| Differential Gain/Phase | 0.02%/0.08° (NTSC, RL = 150Ω) - meets broadcast-grade video fidelity requirements for set-top boxes and surveillance. |
Pinout & Package
The MAX4380EXT+T is housed in a 6-pin SC70 package (3.0mm × 1.7mm × 0.9mm), optimized for space-constrained video and portable designs. Pin 1 is marked with top-side laser trim code "AAV".
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output; rail-to-rail capable; high-impedance when DISABLE = low. |
| 2 | IN− | Inverting input; differential pair node with 70kΩ differential input resistance. |
| 3 | IN+ | Noninverting input; accepts common-mode down to VEE − 0.2V for ground-sensing. |
| 4 | VEE | Negative supply (GND in single-supply); requires local 0.1µF bypass capacitor. |
| 5 | DISABLE | Active-low enable control; logic-low (≤ VCC − 3V) disables output to ~30kΩ impedance. |
| 6 | VCC | Positive supply (4.5V–11V); requires local 0.1µF bypass capacitor adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Output | Swings within 50mV of VCC and VEE under 2kΩ load - preserves >98% of available voltage headroom in 5V systems. |
| High-Speed Disable | 1µs disable time and 100ns enable time - enables precise timing control in video multiplexing and power-gated signal paths. |
| Low Distortion at 5MHz | −63dBc THD and −65dBc SFDR - ensures minimal color bleeding and luminance artifacts in NTSC/PAL video transmission. |
| Unity-Gain Stable | No external compensation required - simplifies PCB layout and eliminates risk of instability in gain-of-1 video buffer configurations. |
| Ultra-Small SC70-6 | 3.0mm × 1.7mm footprint - fits into tight spaces on camera modules and compact video encoder boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Higher 1.7GHz GBW but no disable function; 12.5mA IQ; SO-8 package (larger than SC70-6). | Lacks integrated disable - requires external MOSFET switch for power gating; unsuitable for space-constrained multiplexers. | Choose when maximum bandwidth (>1GHz) is prioritized over size and disable functionality. |
| ADA4891-1ARJZ-R7 | 110MHz bandwidth, 225V/µs slew rate, 3.2mA IQ, SC70-6 package, no disable pin. | Lower speed and no disable - adequate for SD video or lower-frequency instrumentation, but not for HD video line driving. | Choose for cost-sensitive, non-multiplexed 5V applications where 210MHz is unnecessary. |
Compared with LMH6702MF/NOPB and ADA4891-1ARJZ-R7, the MAX4380EXT+T uniquely combines SC70-6 size, 210MHz bandwidth, rail-to-rail output, and active disable in a single device - enabling compact, low-power, high-fidelity video signal routing unattainable with either alternative alone.

FAQ
What is the operating temperature range for the MAX4380EXT+T?
The MAX4380EXT+T is rated for operation from −40°C to +85°C, matching the industrial temperature grade specified in the ordering information table. This range is validated across all electrical parameters including bandwidth, slew rate, and distortion performance, ensuring reliability in outdoor surveillance systems and portable test equipment where ambient temperatures fluctuate widely. The MAX4380EXT+T maintains its 210MHz −3dB bandwidth and 485V/µs slew rate across this full range.
Does the MAX4380EXT+T require external compensation for unity-gain stability?
No, the MAX4380EXT+T is internally compensated for unity-gain stability. The datasheet explicitly states "internally compensated for unity gain" and recommends a 24Ω series feedback resistor (RF) in unity-gain configurations to optimize AC response by damping parasitic LC resonance. No external capacitors or network compensation is needed, simplifying layout and eliminating stability risks in video buffer applications. This applies directly to the MAX4380EXT+T in its SC70-6 package.
What is the output impedance of the MAX4380EXT+T in disabled mode?
In disabled mode (DISABLE pin pulled low), the MAX4380EXT+T output presents a high-impedance state with a typical resistance of 30kΩ and maximum of 35kΩ, as specified in the DC Electrical Characteristics table under "Disabled Output Resistance". This value is measured across the full output voltage range (0V to 5V) and ensures minimal loading on downstream multiplexers or shared video buses. The MAX4380EXT+T also exhibits only 2pF output capacitance in this state, preserving signal integrity in RF/video switching applications.
Can the MAX4380EXT+T drive a 75Ω video load effectively?
Yes, the MAX4380EXT+T is explicitly characterized for 75Ω loads in video applications. Its datasheet specifies output voltage swing (VOL − VEE and VCC − VOH) and output current (±25mA to ±50mA) under 75Ω conditions, and lists "Video Line Driver" as a primary application. With 0.02% differential gain and 0.08° differential phase error at NTSC frequencies, it meets broadcast video fidelity standards. The MAX4380EXT+T maintains 40MHz 0.1dB gain flatness into 75Ω, ensuring flat frequency response across the entire baseband video spectrum.
What is the input common-mode voltage range of the MAX4380EXT+T with a +5V single supply?
With a +5V single supply (VEE = 0V), the MAX4380EXT+T input common-mode voltage range extends from −0.2V to +2.75V, as guaranteed by CMRR testing and confirmed in the DC Electrical Characteristics table. This allows the device to accept ground-referenced signals (e.g., from sensors or DACs) and operate linearly with inputs below the negative rail - a key requirement for true "ground-sensing" front-end amplifiers. The MAX4380EXT+T maintains high CMRR (>70dB) across this full range, ensuring accurate signal reproduction without offset drift.
