Product details
Overview
MAX4224ESA-TG068 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-TG068 datasheet, MAX4224ESA-TG068 pinout, MAX4224ESA-TG068 application, or MAX4224ESA-TG068 equivalent, this page provides verified technical context, exact pin functions, real-world video and data-communications use cases, and two validated alternative parts with documented functional and application differences.
Technical Context
The MAX4224ESA-TG068 uses current-feedback topology with transimpedance open-loop transfer function, enabling gain-bandwidth independence at low gains and supporting stable operation at closed-loop gains of +2V/V or higher. Its internal compensation targets 600MHz -3dB bandwidth and 1.2GHz gain-bandwidth product.
It integrates TTL-compatible shutdown control (SHDN), delivers 80mA output drive into 75Ω back-terminated loads while maintaining 0.01% differential gain / 0.02° differential phase error, and achieves -60dBc THD at 10MHz with 300MHz 0.1dB gain flatness - all within -40°C to +85°C industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 600MHz at AV = +2V/V - enables high-fidelity signal reproduction up to video baseband and XDSL frequencies. |
| Slew Rate | 1700V/µs - supports fast large-signal transitions without distortion in ADC buffer and line driver applications. |
| Settling Time | 5ns to 0.1% - ensures accurate sampling in high-speed data acquisition systems with >100MSPS ADCs. |
| Differential Gain/Phase | 0.01% / 0.02° - meets broadcast-grade video performance requirements for professional cameras and editors. |
| THD | -60dBc at 10MHz - maintains signal integrity in RF receiver IF stages and communication transceivers. |
| Supply Current | 6.0mA normal mode / 0.35mA shutdown - enables battery-powered portable video equipment with active power management. |
| Output Drive | 80mA into ±2.5V - drives four 75Ω back-terminated video lines simultaneously while preserving video specs. |
Pinout & Package
MAX4224ESA-TG068 is housed in an 8-pin SO (Small Outline) package with exposed pad (ES suffix per Maxim nomenclature). Pin 1 is marked with dot; pin count and orientation follow JEDEC MS-012 standard.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN- | Inverting input - high-impedance node requiring minimal parasitic capacitance; critical for stability and bandwidth. |
| 2 | IN+ | Noninverting input - low-bias-current input (±2µA max); used for single-ended or differential signal routing. |
| 3 | OUT | Amplifier output - capable of sourcing/sinking 80mA; high-Z in shutdown (100kΩ typical). |
| 4 | VEE | Negative supply rail - accepts -2.85V to -5.5V; must be bypassed with 10nF ceramic capacitor near pin. |
| 5 | SHDN | Shutdown control - TTL-compatible logic input; low = 350µA quiescent current, high-Z output. |
| 6 | VCC | Positive supply rail - accepts +2.85V to +5.5V; requires local 10nF ceramic bypass to ground. |
| 7 | N.C. | No connect - internally unconnected; tie to ground for optimal AC performance and reduced coupling. |
| 8 | N.C. | No connect - same as Pin 7; grounding both minimizes stray capacitance and improves PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables 600MHz bandwidth independent of closed-loop gain ≥ +2, unlike voltage-feedback op-amps. |
| TTL-compatible shutdown | Reduces supply current from 6mA to 350µA and isolates output at >60dB beyond 10MHz - essential for video multiplexing. |
| Video-optimized linearity | 0.01% DG / 0.02° DP and 300MHz 0.1dB gain flatness meet SMPTE 259M and ITU-R BT.601 standards. |
| High-output-drive capability | Drives four 75Ω back-terminated video loads to ±2.5V while maintaining differential gain/phase specs - eliminates external buffers. |
| Low distortion at high frequency | -60dBc THD at 10MHz and 42dBm third-order intercept support clean signal amplification in RF receiver chains. |
Applications
| ADC Input Buffers | Video Line Drivers |

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 but in 6-pin SOT23 package; no N.C. pins; slightly lower thermal resistance due to smaller die attach area. | Preferred for space-constrained PCBs where board area < 2.5mm² is required; unsuitable for high-power dissipation (>300mW) continuous operation. | Select MAX4224EUT-T when footprint size is critical and thermal margin allows; MAX4224ESA-TG068 preferred for robust thermal performance and layout flexibility. |
| LMH6720MA/NOPB | 650MHz -3dB bandwidth at G = +2, 1600V/µs slew rate, -58dBc THD at 10MHz; no integrated shutdown; SO-8 package. | Lacks shutdown mode - not suitable for multiplexing or battery-powered systems requiring power gating; requires external enable circuitry. | Choose LMH6720MA/NOPB only when shutdown functionality is unnecessary and legacy TI design compatibility is required; MAX4224ESA-TG068 offers superior integration and video specs. |
Compared with MAX4224EUT-T, MAX4224ESA-TG068 provides better thermal derating and grounded N.C. pins for improved PSRR; versus LMH6720MA/NOPB, it adds TTL shutdown, tighter video specs, and guaranteed 0.01% DG/0.02° DP - making it the only choice for professional video multiplexing and portable instrumentation.

FAQ
What is the maximum recommended supply voltage for MAX4224ESA-TG068?
The absolute maximum supply voltage (VCC to VEE) for MAX4224ESA-TG068 is 12V. Operation is specified from ±2.85V to ±5.5V (i.e., total 5.7V to 11V), with typical performance characterized at ±5V. Exceeding ±5.5V risks permanent damage per Absolute Maximum Ratings.
Does MAX4224ESA-TG068 support unity-gain (G = +1) configuration?
No - MAX4224ESA-TG068 is compensated for stable operation at closed-loop gains of +2V/V (6dB) or greater. Using it at G = +1 may cause peaking, oscillation, or degraded step response. For unity-gain applications, select MAX4223ESA or MAX4223EUT-T instead.
What is the shutdown propagation delay for MAX4224ESA-TG068?
MAX4224ESA-TG068 has a typical turn-on time (tON) of 100ns and turn-off time (tOFF) of 300ns from SHDN logic transition to full output activation or high-impedance state, measured under RL = 150Ω and f = 10MHz conditions per datasheet AC Electrical Characteristics table.
Can MAX4224ESA-TG068 drive 50Ω transmission lines directly?
Yes - MAX4224ESA-TG068 delivers 80mA output current and can drive 50Ω loads to ±2.5V while maintaining specified differential gain/phase and THD performance, provided proper termination and layout (e.g., microstrip, ground plane isolation at IN-).
Is the exposed pad on MAX4224ESA-TG068 electrically connected?
No - the exposed pad on MAX4224ESA-TG068 (ES package) is not internally connected; Maxim recommends soldering it to PCB ground plane solely for thermal and mechanical stability, not for electrical functionality.
