Product details
Overview
The MAX4225ESA+ from Maxim Integrated is a dual-channel, low-power, current-feedback amplifier optimized for closed-loop gain ≥ +1 (0dB), delivering 1GHz -3dB bandwidth, 1100V/µs slew rate, and 0.01%/0.02° differential gain/phase error-ideal for high-fidelity video line drivers and ADC input buffering in professional broadcast equipment.
For engineers reviewing the MAX4225ESA+ datasheet, MAX4225ESA+ pinout, MAX4225ESA+ application, or MAX4225ESA+ equivalent, key selection criteria include its dual-amplifier SOT23-8 package, shutdown-enabled multiplexing capability (350µA quiescent current, 100kΩ output impedance in shutdown), and verified performance driving four back-terminated 75Ω video loads to ±2.5V while maintaining <0.1dB gain flatness to 300MHz.
Technical Context
The MAX4225ESA+ implements a current-feedback topology with transimpedance open-loop transfer function, enabling gain-bandwidth independence at low gains and supporting stable operation with RF = 560Ω for AV = +1 configurations. Its dual amplifiers share independent shutdown inputs (SHDNA/SHDNB), allowing per-channel power gating without affecting adjacent channel performance.
Each amplifier features matched input resistance (RIN+ ≈ 700kΩ, RIN− ≈ 45kΩ), 6mA quiescent supply current per channel in normal mode, and rail-to-rail output swing capability (±2.5V into 50Ω) across the full −40°C to +85°C industrial temperature range-enabling direct interface with standard video signal levels and high-speed data converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 1GHz at AV = +1 - supports full HD/3G-SDI baseband video signal integrity without attenuation |
| Slew Rate | 1100V/µs - ensures ≤8ns settling to 0.1% for fast transient response in ADC sampling circuits |
| Differential Gain/Phase Error | 0.01% / 0.02° - meets SMPTE 259M broadcast video fidelity requirements |
| THD | −60dBc at 10MHz - minimizes harmonic distortion in wideband analog signal chains |
| Supply Current (per amp) | 6.0mA typical - enables dual-channel operation within 12mA total budget for portable video systems |
| Shutdown Current (per amp) | 350µA - reduces system standby power by >94% versus active mode |
| Output Drive | 80mA - drives up to four 75Ω back-terminated video lines simultaneously while preserving DG/DP specs |
Pinout & Package
MAX4225ESA+ uses an 8-pin SO (Small Outline) package with exposed pad for thermal enhancement. Pin functions are validated per Maxim's official datasheet revision 2a (19-1230).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply rail | Accepts +2.85V to +5.5V; requires local 10nF ceramic bypass to ground |
| VEE | Negative supply rail | Accepts −2.85V to −5.5V; symmetric dual-supply operation required for full dynamic range |
| INA+, INA− | Amplifier A differential inputs | Current-feedback architecture: IN− sets feedback node impedance; layout must minimize stray capacitance here |
| OUTA | Amplifier A output | Capable of ±2.5V swing into 50Ω; high-Z in shutdown when SHDNA = GND |
| SHDNA | Amplifier A shutdown control | TTL-compatible input; low = 350µA quiescent current, high-Z output; no external pull-up needed |
| INB+, INB− | Amplifier B differential inputs | Matched to INA+/INA−; enables independent dual-channel gain staging |
| OUTB | Amplifier B output | Electrically isolated from OUTA; allows true dual-output video distribution or mux applications |
| SHDNB | Amplifier B shutdown control | Independent of SHDNA; enables per-channel power gating for dynamic load management |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent shutdown controls | Enables per-channel power gating for video multiplexing without cross-talk or loading effects |
| 0.1dB gain flatness to 300MHz | Preserves amplitude integrity across entire NTSC/PAL/HD-SDI baseband spectrum |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4226ESA+ | Same pinout, identical electrical specs, but rated for extended −40°C to +85°C range with 100% production test at +25°C only (vs. guaranteed over temp for MAX4225ESA+) | Preferred for cost-sensitive industrial video where full temperature characterization is not required | Select MAX4226ESA+ only if full −40°C to +85°C guaranteed AC specs are unnecessary |
| LMH6720MA/NOPB | Single-channel, 1.6GHz bandwidth, no shutdown, higher 12.5mA supply current, different SO-8 pinout (no SHDN pins) | Suitable for non-mux, single-path high-speed analog signal chains where power gating is irrelevant | Choose LMH6720MA/NOPB only when dual-channel shutdown and video-optimized DG/DP are not required |
Compared with MAX4226ESA+, the MAX4225ESA+ provides fully characterized AC performance across −40°C to +85°C and tighter production testing; compared with LMH6720MA/NOPB, it delivers dual-channel integration, per-amplifier shutdown, and broadcast-grade video specifications in the same SO-8 footprint-reducing board area and system power by 50% in multiplexed video architectures.

FAQ
What is the operating supply voltage range for the MAX4225ESA+?
The MAX4225ESA+ operates from dual supplies ranging from ±2.85V to ±5.5V. This corresponds to a total supply voltage range of 5.7V to 11V. Operation outside this range violates Absolute Maximum Ratings and may cause permanent damage. The device is specified for full performance across the entire −40°C to +85°C temperature range within these supply limits, and its shutdown mode remains functional down to ±2.85V.
Does the MAX4225ESA+ support unity-gain stable operation?
Yes, the MAX4225ESA+ is optimized for closed-loop gains of +1 (0dB) or greater and is unity-gain stable. Its 1GHz −3dB bandwidth and 0.1dB gain flatness to 300MHz are explicitly specified for AV = +1 configurations using RF = 560Ω. Unlike the +2-gain-optimized MAX4224/MAX4227/MAX4228 variants, the MAX4225ESA+ maintains stability and performance without requiring minimum gain constraints.
How does the shutdown feature work on the MAX4225ESA+?
The MAX4225ESA+ has two independent shutdown inputs: SHDNA and SHDNB. Driving either pin low (≤0.8V) places its corresponding amplifier into low-power shutdown, reducing supply current to 350µA and placing the output in a high-impedance state (~100kΩ). Both amplifiers remain fully functional when their respective SHDN pins are high (≥2.0V). No external pull-up resistors are required-the internal logic accepts TTL-level signals directly.
Can the MAX4225ESA+ drive 75Ω video loads with proper back-termination?
Yes, the MAX4225ESA+ is explicitly characterized to drive up to four back-terminated 75Ω video loads simultaneously to ±2.5V while maintaining its specified differential gain/phase error (0.01%/0.02°) and 0.1dB gain flatness to 300MHz. This capability is confirmed in the datasheet's "Features" section and supported by its 80mA output current rating and robust large-signal bandwidth (330MHz).
What is the input common-mode voltage range for the MAX4225ESA+?
The MAX4225ESA+ has an input common-mode voltage range of ±2.5V (i.e., −2.5V to +2.5V) when operated with ±5V supplies. This range scales linearly with supply voltage-for example, with ±3V supplies, the range is ±1.71V. The specification is derived from the DC Electrical Characteristics table and confirmed by the "Input Common-Mode Voltage Range" parameter (VCM = ±2.5V min) under standard test conditions (VCC = +5V, VEE = −5V).
