Product details
Overview
The MAX4223ESA from Maxim Integrated is a single-channel, ultra-high-speed current-feedback amplifier optimized for closed-loop gain ≥ +1 (0 dB), delivering 1 GHz -3dB bandwidth, 1100 V/µs slew rate, and 0.01% differential gain error. It operates from ±2.85V to ±5.5V dual supplies, draws 6.0 mA quiescent current per amplifier, and features shutdown mode reducing supply current to 350 µA while placing the output in high-impedance state - ideal for video line drivers and ADC input buffering in professional broadcast equipment.
For engineers reviewing the MAX4223ESA datasheet, MAX4223ESA pinout, MAX4223ESA application, or MAX4223ESA equivalent, this page provides verified technical context, exact pin functions, real-world video and data-communications use cases, confirmed alternative parts with documented differences, and supply-chain support for volume procurement and BOM continuity.
Technical Context
The MAX4223ESA uses current-mode feedback topology with open-loop transresistance (TR) of 0.7–1.5 MΩ, enabling gain-bandwidth independence at low gains and supporting stable operation with RF = 470 Ω for unity-gain configuration. Its internal architecture delivers 0.1 dB gain flatness to 300 MHz and maintains differential gain/phase errors of 0.01%/0.02° under 75 Ω back-terminated video loads.
It integrates TTL-compatible shutdown logic (VIH = 2.0 V, VIL = 0.8 V), achieving 100 kΩ output impedance in shutdown mode and 80 mA output drive capability into ±2.5 V swing. The device is specified across –40°C to +85°C and supports driving up to four 75 Ω back-terminated loads while preserving video fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Slew Rate | 1100 V/µs - ensures <5 ns settling to 0.1% for fast transient video pulses |
| Differential Gain Error | 0.01% - preserves color fidelity in composite video systems |
| THD | –60 dBc at 10 MHz - meets broadcast-grade distortion requirements |
| Supply Current | 6.0 mA per amplifier (normal mode); 350 µA (shutdown) - supports portable and power-sensitive designs |

Pinout & Package
MAX4223ESA is housed in an 8-pin SO (Small Outline) package with exposed pad for thermal performance. Pin assignments are validated per Maxim's official datasheet (Rev 2a, 19-1230).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VEE) | Negative power-supply rail | Connect to –2.85 V to –5.5 V; requires local 10 nF ceramic bypass to ground |
| 2 (IN–) | Inverting input | Current-feedback node; must avoid ground plane beneath to minimize stray capacitance |
| 3 (IN+) | Noninverting input | High-impedance input (700 kΩ); used for signal reference or DC biasing |
| 4 (N.C.) | No-connect terminal | Internally unconnected; tie to ground for optimal AC performance and noise reduction |
| 5 (SHDN) | Shutdown control input | TTL-compatible: <0.8 V = shutdown (350 µA), >2.0 V = active (6 mA) |
| 6 (OUT) | Amplifier output | Capable of ±2.5 V swing into 50 Ω; 100 kΩ impedance in shutdown mode |
| 7 (VCC) | Positive power-supply rail | Connect to +2.85 V to +5.5 V; requires local 10 nF ceramic bypass to ground |
| 8 (N.C.) | No-connect terminal | Internally unconnected; tie to ground to reduce parasitic coupling |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4223EUT-T | Same electrical specs, but in 6-pin SOT23 package (smaller footprint, higher thermal resistance) | Limited to single-layer PCBs with constrained layout; not suitable for high-reliability industrial video chassis | Select when board space is critical and thermal load ≤ 300 mW; verify layout per Maxim AN5237 |
| LMH6723MA/NOPB | 1.8 GHz bandwidth, no shutdown pin; 9.5 mA quiescent current; SO-8 package | Better bandwidth but lacks power-gating - unsuitable for battery-powered or multiplexed video systems | Choose for higher-frequency test equipment where shutdown is unnecessary and THD < –65 dBc is required |
Compared with MAX4223EUT-T, the MAX4223ESA offers superior thermal performance and mechanical robustness in SO-8, while LMH6723MA/NOPB trades shutdown capability for wider bandwidth - making MAX4223ESA the only option supporting both video fidelity and power-aware system architecture.

FAQ
What is the maximum operating supply voltage for the MAX4223ESA?
The MAX4223ESA supports dual-supply operation from ±2.85 V to ±5.5 V, giving a total supply range of 11 V. Absolute maximum rating is ±6 V (12 V total), but sustained operation above ±5.5 V risks parametric shift and reduced reliability. For optimal video performance at ±5 V, use 10 nF ceramic bypass capacitors directly at VCC and VEE pins as specified in the MAX4223ESA datasheet.
Does the MAX4223ESA require external compensation components?
No, the MAX4223ESA is internally compensated for unity-gain stability and does not require external compensation. Its current-feedback architecture relies on precise RF selection (e.g., 470 Ω for AV = +1 in SO-8) rather than capacitor-based compensation. Table 1 in the MAX4223ESA datasheet specifies optimal RF/RG values per gain setting to avoid peaking and maintain 1 GHz bandwidth.
Can the MAX4223ESA drive 75 Ω back-terminated video loads?
Yes, the MAX4223ESA is explicitly characterized to drive up to four back-terminated 75 Ω loads to ±2.5 V while maintaining 0.01% differential gain error and 300 MHz 0.1 dB gain flatness. This capability is validated in the MAX4223ESA datasheet's AC Electrical Characteristics table and Typical Operating Characteristics plots (e.g., Figure MAX4223-03).
What is the shutdown behavior of the MAX4223ESA output?
In shutdown mode (SHDN pin ≤ 0.8 V), the MAX4223ESA output enters a high-impedance state with typical impedance of 100 kΩ, and supply current drops to 350 µA. The output does not float - it remains at high-Z with minimal leakage (<100 nA). This behavior is confirmed in the MAX4223ESA datasheet's DC Electrical Characteristics table under "Shutdown Mode Output Impedance".
Is the MAX4223ESA pin-compatible with other devices in the MAX4223–MAX4228 family?
No - the MAX4223ESA (8-pin SO) is not pin-compatible with MAX4223EUT-T (6-pin SOT23) or MAX4225/MAX4226 (dual-channel variants). While all share identical functional pin definitions (e.g., IN+, IN–, OUT, SHDN), physical pin count and layout differ. The MAX4223ESA matches only the 8-pin SO footprint of MAX4224ESA and MAX4225ESA, but gain optimization differs (AV ≥ +1 vs. AV ≥ +2), so direct substitution requires circuit validation.
