Analog Devices Inc./Maxim Integrated MAX4104ESA

Overview

The MAX4104ESA from Maxim Integrated is a unity-gain-stable, ultra-high-speed voltage-feedback operational amplifier in a 5-pin SOT23 package. It delivers 625MHz -3dB bandwidth, 400V/µs slew rate, and 2.1nV/√Hz input voltage noise density while consuming only 20mA supply current. Designed for video ADC preamplification and high-fidelity signal conditioning, it supports ±3.7V output swing into 100Ω loads with ±70mA drive capability.

For engineers reviewing the MAX4104ESA datasheet, MAX4104ESA pinout, MAX4104ESA application, or MAX4104ESA equivalent, key selection criteria include unity-gain stability, low-noise performance at 1MHz, differential gain/phase error of 0.01%/0.01° (NTSC), and compatibility with ±3.5V to ±5.5V dual supplies in space-constrained layouts.

Technical Context

The MAX4104ESA employs a voltage-feedback architecture optimized for unity-gain stability, enabling direct use in non-inverting and inverting configurations without external compensation. Its internal design achieves 0.1dB gain flatness up to 100MHz and maintains -88dBc spurious-free dynamic range at 5MHz with 100Ω load.

It features rail-to-rail output swing capability (±3.7V) under heavy loading and integrates matched input transistors to ensure low input offset voltage (±1mV typical) and drift (8µV/°C). The device operates across -40°C to +85°C and is specified for dual-supply operation only - no single-supply functionality is supported.

Key Specifications

Pinout & Package

MAX4104ESA is housed in a 5-pin SOT23-5 surface-mount package with exposed pad (not electrically connected), footprint compatible with JEDEC MO-178AA. Pin 1 is marked by a dot or beveled edge; pin numbering follows standard SOT23 counterclockwise orientation.

FAQ

What is the maximum recommended supply voltage for the MAX4104ESA?

The MAX4104ESA has an absolute maximum supply voltage of ±5.5V per rail, with a recommended operating range of ±3.5V to ±5.5V. Exceeding ±5.5V risks permanent damage. The device is specified for dual-supply operation only - single-supply use is not supported, and VEE must remain negative relative to ground. Operation at ±5V yields optimal AC performance per the datasheet test conditions.

Does the MAX4104ESA support rail-to-rail input or output operation?

The MAX4104ESA does not support rail-to-rail input operation: its input common-mode voltage range is limited to –2.8V to +4.1V with ±5V supplies. However, it delivers rail-to-rail output swing capability - achieving ±3.7V into 100kΩ and ±3.5V into 100Ω loads. This makes the MAX4104ESA suitable for driving standard video levels but not for applications requiring full input voltage range utilization near supply rails.

Can the MAX4104ESA drive a 75Ω coaxial cable directly?

Yes, the MAX4104ESA can directly drive a 75Ω coaxial cable when configured as a back-terminated line driver (e.g., with 75Ω series resistor at the output and 75Ω load at the far end). Its ±70mA output current drive and ±3.7V swing ensure compliance with NTSC/PAL signal levels. Layout best practices - including microstrip routing, ground plane integrity, and local 0.1µF + 1nF bypassing - are essential to maintain signal fidelity and prevent reflections.

What is the typical input bias current of the MAX4104ESA at +25°C?

The typical input bias current of the MAX4104ESA at +25°C is 32µA for the inverting input (IN–) and 34µA for the noninverting input (IN+), resulting in a typical input offset current of 2µA. These values increase with temperature, reaching up to 40µA at +85°C. For precision DC-coupled applications, these bias currents must be accounted for in gain-setting resistor selection to minimize output offset error.

Is the MAX4104ESA pin-compatible with other devices in the MAX4104/MAX4304 family?

Yes, the MAX4104ESA shares identical pinout and package (5-pin SOT23-5) with MAX4105ESA, MAX4304ESA, and MAX4305ESA. However, internal compensation differs: MAX4104ESA is unity-gain stable, while MAX4304ESA requires minimum gain ≥2V/V, MAX4105ESA ≥5V/V, and MAX4305ESA ≥10V/V. Swapping devices without adjusting external gain-setting resistors will result in instability or degraded bandwidth.
