Product details
Overview
The MAX4224ESA from Maxim Integrated is a single-channel, current-feedback operational amplifier optimized for closed-loop gain ≥ +2 (6dB), delivering 600MHz -3dB bandwidth, 1700V/µs slew rate, and 5ns 0.1% settling time. It operates on ±2.85V to ±5.5V dual supplies, draws 6mA quiescent current, and features shutdown mode reducing supply current to 350µA while placing output in high-impedance state - ideal for video line drivers and multiplexed ADC input buffering.
For engineers reviewing the MAX4224ESA datasheet, MAX4224ESA pinout, MAX4224ESA application, or MAX4224ESA equivalent, key selection criteria include gain-stability at +2V/V, differential gain/phase error (0.01%/0.02°), 0.1dB gain flatness to 300MHz, THD of –60dBc at 10MHz, and SOT23-6 package compatibility with space-constrained high-speed analog designs.
Technical Context
The MAX4224ESA uses current-feedback architecture with transimpedance open-loop transfer function, enabling gain-bandwidth independence at low gains and supporting stable operation at closed-loop gains ≥ +2V/V. Its internal compensation targets 600MHz –3dB bandwidth and 1.2GHz gain-bandwidth product, with RF/RG network sensitivity dictating peaking and bandwidth trade-offs.
Shutdown control is TTL-compatible (SHDN logic low = 0.8V max, logic high = 2.0V min), activating a high-impedance output state (100kΩ typical) and reducing supply current to 350µA per amplifier. Input stage features matched 700kΩ noninverting and 45kΩ inverting input resistances, with ±2.5V output swing into 50Ω and 80mA drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 600MHz at AV = +2V/V - enables baseband video and high-speed data transmission up to 300MHz with 0.1dB flatness. |
| Slew Rate | 1700V/µs - supports clean 2V-step transitions in under 1.2ns, critical for driving fast ADC inputs without slewing distortion. |
| Settling Time | 5ns to 0.1% - ensures accurate sampling of multi-MHz video or communication waveforms within tight timing windows. |
| THD | –60dBc at 10MHz, RL = 150Ω - meets broadcast-grade video linearity requirements and minimizes intermodulation in RF receiver IF stages. |
| Differential Gain/Phase | 0.01% / 0.02° - preserves color fidelity and timing integrity in professional SD/HD video signal chains. |
| Supply Current | 6.0mA normal mode, 0.35mA shutdown - enables battery-powered portable video equipment and power-gated multiplexer architectures. |
| Output Drive | 80mA into ±2.5V - drives four back-terminated 75Ω video loads simultaneously while maintaining specified DG/DP performance. |
Pinout & Package
The MAX4224ESA is housed in a 6-pin SOT23 package (JEDEC MO-178AA), with exposed pad not electrically connected. Pin 1 is marked via top-side laser etch (top mark: AAAD), and device orientation follows standard SOT23 pin 1 indicator (notch or dot).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VEE) | Negative power-supply terminal | Connect to –2.85V to –5.5V rail; requires local 10nF ceramic bypass to ground plane. |
| 2 (IN–) | Inverting input | High-impedance current-summing node; must avoid ground plane beneath to minimize stray capacitance and peaking. |
| 3 (IN+) | Noninverting input | 700kΩ input resistance; used for reference biasing or single-ended-to-differential conversion. |
| 4 (N.C.) | No-connect terminal | Internally unconnected; tie to ground plane to reduce parasitic coupling in high-frequency layouts. |
| 5 (SHDN) | Shutdown control input | TTL-compatible enable: ≤0.8V = shutdown (350µA, high-Z output), ≥2.0V = active (6mA, full drive). |
| 6 (OUT) | Amplifier output | Capable of sourcing/sinking 80mA; requires surface-mount 75Ω back-termination for video line driving. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback topology | Enables 600MHz bandwidth independent of gain ≥ +2V/V, eliminating gain-vs-bandwidth trade-off seen in voltage-feedback amplifiers. |
| Video-optimized linearity | 0.01% differential gain and 0.02° differential phase errors ensure broadcast-compliant NTSC/PAL signal reproduction. |
| Low-power shutdown | Reduces supply current to 350µA and raises output impedance to 100kΩ, enabling passive multiplexing of multiple video channels. |
| High-output drive | Delivers ±2.5V into 50Ω or drives four 75Ω back-terminated lines - eliminates need for external buffer stages in video distribution. |
| Ultrafast settling | 5ns to 0.1% allows precise sampling of 100+ MSPS ADC inputs without aperture uncertainty degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4224EUT-T | Same electrical specs and gain optimization (+2V/V), but in SOT23-6 with tape-and-reel packaging and top mark AAAD - identical pinout and thermal profile. | Optimized for automated SMT assembly; same PCB footprint and layout rules apply. | Select MAX4224EUT-T for volume production requiring reel delivery and RoHS-compliant packaging. |
| LMH6720MA | 650MHz –3dB bandwidth at +2V/V, 1900V/µs slew, no integrated shutdown; higher 12.5mA quiescent current. | Lacks shutdown mode - unsuitable for multiplexing or battery-powered video systems requiring dynamic power gating. | Choose LMH6720MA only when maximum bandwidth margin is required and shutdown functionality is unnecessary. |
Compared with MAX4224EUT-T, the MAX4224ESA shares identical performance and pinout but differs in packaging qualification (tube vs. tape-and-reel); versus LMH6720MA, MAX4224ESA trades 50MHz bandwidth for 6.5× lower quiescent current and integrated shutdown - critical for portable and multiplexed video systems.

FAQ
What is the minimum stable closed-loop gain for the MAX4224ESA?
The MAX4224ESA is compensated for stable operation at closed-loop gains of +2V/V (6dB) or greater. Attempting unity-gain (AV = +1) configurations may cause peaking or oscillation due to insufficient phase margin. For +1V/V applications, use the MAX4223ESA instead, which is explicitly optimized for that gain configuration.
Does the MAX4224ESA support single-supply operation?
No, the MAX4224ESA requires dual supplies ranging from ±2.85V to ±5.5V. Its input common-mode range is specified from ±2.5V, and output swing is symmetrical about ground. Single-supply operation is not supported - for 3V–5V single-rail applications, consider the MAX44263 or similar rail-to-rail voltage-feedback alternatives.
What is the recommended feedback resistor value for MAX4224ESA at AV = +2V/V?
The datasheet specifies RF = RG = 470Ω as the optimal network for AV = +2V/V in SOT23-6 packages. This combination delivers 600MHz –3dB bandwidth with minimal peaking. Deviating significantly (e.g., RF < 300Ω or > 680Ω) degrades stability or bandwidth - always verify AC response with simulation and bench measurement.
How does shutdown mode affect output impedance and isolation on the MAX4224ESA?
In shutdown mode (SHDN ≤ 0.8V), the MAX4224ESA output impedance rises to 100kΩ typical, and off-isolation exceeds 65dB at 3.58MHz. This high-Z state prevents loading of adjacent active channels in multiplexed video buses and enables true analog switching without external relays or MOSFETs.
Can the MAX4224ESA drive 75Ω back-terminated video lines directly?
Yes - the MAX4224ESA delivers ±2.5V into 50Ω and is characterized to drive up to four back-terminated 75Ω loads simultaneously while maintaining 0.01%/0.02° differential gain/phase. Use surface-mount 75Ω resistors placed immediately at the OUT pin, and route traces as controlled-impedance microstrips for optimal return loss.
