Analog Devices Inc./Maxim Integrated MAX4386EESD+

Overview

MAX4386EESD+ from Maxim Integrated is a quad, rail-to-rail output, voltage-feedback operational amplifier optimized for high-speed video line driving and RF signal conditioning. It delivers 230MHz -3dB bandwidth, 450V/µs slew rate, ±15kV HBM ESD protection, and operates from a single 5V supply with input common-mode range extending beyond VEE. It is used in surveillance video systems and set-top box video routing where robustness against external ESD events and wide dynamic range are critical.

For engineers reviewing the MAX4386EESD+ datasheet, MAX4386EESD+ pinout, MAX4386EESD+ application, or MAX4386EESD+ equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions for the 14-pin SO package, confirmed video/RF use cases, and two rigorously cross-checked alternative parts with documented functional and application-level differences.

Technical Context

The MAX4386EESD+ employs current-feedback techniques within a voltage-feedback architecture to achieve both unity-gain stability and high slew rate (450V/µs). Its input stage supports common-mode voltages down to VEE − 0.2V and up to VCC − 2.25V, enabling ground-sensing operation in single-supply systems.

It features four fully independent amplifiers in one SO-14 package, each with rail-to-rail output swing (within 50mV of rails into 2kΩ), low differential gain/phase error (0.02%/0.01°), and integrated ±15kV IEC 1000-4-2 air-gap and contact discharge protection on all pins - eliminating need for external TVS diodes in exposed video interfaces.

FAQ

What is the operating supply voltage range for MAX4386EESD+?

The MAX4386EESD+ operates from a single 4.5V to 5.5V supply, with guaranteed performance across the full -40°C to +85°C temperature range. Its power-supply rejection ratio (PSRR) remains 50–62dB across this voltage window, ensuring stable operation even with noisy or drooping 5V rails commonly found in video subsystems. This range aligns precisely with standard 5V logic and analog video supply domains.

Does MAX4386EESD+ support rail-to-rail input operation?

No, MAX4386EESD+ does not support rail-to-rail input. Its input common-mode voltage range extends from VEE − 0.2V to VCC − 2.25V - meaning it senses down to ground (when VEE = 0V) but cannot accept signals within 2.25V of VCC. This ground-sensing capability enables single-supply video applications, but input signals must stay below 2.75V when powered from 5V. The output, however, is fully rail-to-rail.

What is the maximum capacitive load the MAX4386EESD+ can drive stably?

The MAX4386EESD+ is not optimized for direct capacitive loading. Stability degrades above ~10pF without isolation. For loads >10pF, a series isolation resistor (10Ω–27Ω, value dependent on capacitance per Figure 3 in the datasheet) must be placed between the output and the capacitor. At 68pF, a 15Ω resistor restores flat frequency response; at 120pF, 27Ω is recommended. This requirement applies to all four channels of MAX4386EESD+ identically.

How does the ESD protection on MAX4386EESD+ compare to external TVS diodes?

The MAX4386EESD+ integrates ±15kV HBM, ±8kV IEC 1000-4-2 contact, and ±15kV air-gap ESD protection on every pin - matching or exceeding the protection level of discrete 0402 TVS diodes used in video interfaces. Unlike external diodes, this on-die protection adds zero capacitance (<0.5pF), avoids signal degradation, and eliminates layout complexity. It is characterized per IEC test circuits (Figure 6), making MAX4386EESD+ a true single-component solution for Level 4 system ESD compliance.

Can MAX4386EESD+ be used in inverting amplifier configurations?

Yes, MAX4386EESD+ supports both inverting and noninverting configurations. Its internal compensation ensures unity-gain stability, and application note guidance specifies optimal resistor values (e.g., 24Ω feedback resistor for best AC response in unity-gain). Gain-setting resistors should be kept low (≤100Ω) to avoid bandwidth reduction from parasitic capacitance - a constraint that applies uniformly across all four amplifiers in the MAX4386EESD+.
