Analog Devices Inc./Maxim Integrated MAX4415ESA

Overview

MAX4415ESA from Maxim Integrated is a single-channel, high-speed, rail-to-rail output operational amplifier optimized for closed-loop gains ≥ +5V/V. It delivers 150MHz -3dB bandwidth, 470V/µs slew rate, 1.6mA supply current per amplifier, and operates from a single +2.7V to +5.5V supply. Its low distortion (–79dBc SFDR at 5MHz, 0.01% THD), differential gain/phase of 0.05%/0.35°, and rail-to-rail output make it suitable for video line drivers and baseband signal conditioning in portable communications.

For engineers reviewing the MAX4415ESA datasheet, MAX4415ESA pinout, MAX4415ESA application, or MAX4415ESA equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative op amps with documented performance trade-offs for gain-stable, low-power, high-speed analog signal paths.

Technical Context

The MAX4415ESA uses voltage-feedback architecture with internal compensation tailored for stable operation at closed-loop gains of +5V/V or higher-unlike unity-gain-stable variants (e.g., MAX4414). Its 470V/µs slew rate enables clean 2V_p-p step response with 5ns rise/fall time and 120ns 1% settling time, supporting wideband baseband and video applications without peaking or overshoot when properly isolated from capacitive loads.

It features ground-sensing input (common-mode range extends 100mV below VEE) and rail-to-rail output (within 105mV of rails into 1kΩ), enabling maximum dynamic range in single-supply systems. Input bias current remains ≤4µA over –40°C to +85°C, and output can drive ≥±25mA into 20Ω loads while maintaining <0.05% differential gain error at NTSC video frequencies.

Key Specifications

Pinout & Package

MAX4415ESA is housed in an 8-pin SO (Small Outline) package, RoHS-compliant, with standard JEDEC MS-012AC footprint (5.0mm × 4.0mm, 1.27mm pitch). Thermal resistance θ_JA = 170°C/W; rated for –40°C to +85°C operation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed, low-power op amp applications.

Compared with MAX4414ESA and ADA4891-1ARZ, the MAX4415ESA trades unity-gain stability for higher slew rate and bandwidth at fixed +5V/V gain-making it optimal for gain-block applications in portable video and IF signal chains where distortion and speed are prioritized over configurability.

Availability

MAX4415ESA is available at Aetrix Electronics and suitable for video line drivers, portable ADC front-ends, and baseband IF amplifiers requiring stable component supply, long-term manufacturability, and guaranteed RoHS compliance.

Supply support for MAX4415ESA includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for industrial, medical, and communications applications.

The MAX4414–MAX4419 family targets low-voltage, high-speed portable systems-specifically engineered for video, baseband, and instrumentation signal paths where rail-to-rail operation, ultra-low power, and low distortion are critical.

FAQ

What is the minimum stable closed-loop gain for MAX4415ESA?

The MAX4415ESA is internally compensated for stable operation at closed-loop gains of +5V/V or greater. It is not unity-gain stable; attempting AV = +1V/V may cause peaking or oscillation. For unity-gain applications, use MAX4414ESA instead. The +5V/V minimum gain is explicitly guaranteed in the datasheet's AC Electrical Characteristics table and reinforced by the "compensated for closed-loop gains of +5V/V or greater" statement in the General Description.

Does MAX4415ESA support rail-to-rail input operation?

No, MAX4415ESA does not support rail-to-rail input. Its input common-mode voltage range extends from (VEE – 0.1V) to (VCC – 1.5V), meaning it senses down to 100mV below ground but cannot accept inputs within 1.5V of the positive rail. This ground-sensing capability enables true single-supply interfacing with ground-referenced sources, but high-side input signals require level-shifting or clamping.

Can MAX4415ESA drive a 75Ω coaxial cable directly?

Yes, MAX4415ESA can drive a 75Ω coaxial cable when properly terminated-ideally with back-termination at the load end. The device's low 0.5Ω output impedance at 1MHz and ability to source/sink ±25mA allow robust driving of 75Ω lines. However, for un-terminated or long cables with significant capacitance (>15pF), a 22Ω series isolation resistor is recommended to maintain stability and prevent ringing, as shown in Figure 1 of the datasheet.

What is the typical power-up settling time for MAX4415ESA?

The typical power-up 1% settling time for MAX4415ESA is 1.2µs, as specified in the AC Electrical Characteristics table under "Power-Up 1% Settling Time". This value reflects the time required for the output to stabilize within 1% of final value after VCC reaches regulation. It is critical for power-gated systems or burst-mode instrumentation where rapid turn-on is required without output overshoot.

Is MAX4415ESA pin-compatible with other devices in the MAX4414–MAX4419 family?

MAX4415ESA shares the same 8-pin SO package and pinout as MAX4414ESA, making them physically interchangeable on PCBs. However, they differ electrically: MAX4414ESA is unity-gain stable (400MHz BW, 200V/µs), while MAX4415ESA is +5V/V-gain stable (150MHz BW, 470V/µs). Swapping them requires verifying gain configuration and stability-direct replacement is not functionally safe without circuit review.
