Analog Devices Inc./Maxim Integrated MAX4383ESD

Overview

MAX4383ESD from Maxim Integrated is a quad, rail-to-rail output, high-speed voltage-feedback operational amplifier with disable functionality, delivering 210MHz -3dB bandwidth, 485V/µs slew rate, and 55MHz 0.1dB gain flatness on a +4.5V to +11V single supply. It features ground-sensing inputs, low differential gain/phase error (0.02%/0.08°), and is optimized for video line driving and analog-to-digital converter interface applications.

For engineers reviewing the MAX4383ESD datasheet, MAX4383ESD pinout, MAX4383ESD application, or MAX4383ESD equivalent, this page provides verified circuit role (quad video buffer/amplifier), package mapping (14-pin SO), disable timing (1µs disable time), output drive capability (75mA), and real-world video-system design constraints including 75Ω load compatibility and NTSC-compliant distortion performance.

Technical Context

The MAX4383ESD implements a current-feedback-enhanced voltage-feedback architecture to achieve wide bandwidth and fast settling (16ns to 0.1%). Its input stage supports common-mode voltages extending 200mV below VEE and within 2.25V of VCC, enabling true ground-referenced signal handling in single-supply systems.

All four amplifiers integrate independent disable inputs (DISABLEA–DISABLED) that place outputs into high-impedance state (ROUT(OFF) = 27–35kΩ) with 2pF output capacitance-critical for RF/video multiplexing and power-gated signal routing without loading downstream stages.

Key Specifications

Pinout & Package

FAQ

What is the operating supply voltage range for the MAX4383ESD?

The MAX4383ESD operates from a single +4.5V to +11V supply or dual ±2.25V to ±5.5V supplies. For most video applications, +5V single supply is used, with VEE grounded. The device maintains full AC performance across this range, including 210MHz bandwidth and 485V/µs slew rate at +5V. Absolute maximum supply is +12V between VCC and VEE.

Does the MAX4383ESD support rail-to-rail input common-mode voltage?

The MAX4383ESD supports rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode range extends 200mV below VEE (i.e., to -0.2V on +5V supply) and to within 2.25V of VCC (i.e., up to +2.75V on +5V supply). This "ground-sensing" input enables direct interfacing with 0V-referenced video sources while maintaining high CMRR across the usable range.

How does the disable function work on the MAX4383ESD?

The MAX4383ESD provides individual DISABLE pins (DISABLEA–DISABLED) for each of its four amplifiers. Driving any DISABLE pin low (≤VCC − 3V) places that amplifier's output into a high-impedance state (27–35kΩ) with only 2pF capacitance. Enable time is 100ns; disable time is 1µs. This allows independent channel power gating in video multiplexers without affecting other active channels.

Can the MAX4383ESD drive a 75Ω video load directly?

Yes, the MAX4383ESD is explicitly characterized to drive 75Ω video loads. It delivers 75mA output current and maintains 0.02% differential gain and 0.08° differential phase error into 150Ω (per NTSC test condition), confirming robust performance into standard 75Ω coaxial lines. Output voltage swing remains within 50mV of rails even under 75Ω load, preserving signal headroom.

What is the thermal performance of the MAX4383ESD in its 14-pin SO package?

The MAX4383ESD in 14-pin SO package has a thermal derating factor of 8.3mW/°C above +70°C, with maximum continuous power dissipation of 667mW at +70°C. At room temperature, typical quiescent supply current is 7.5–10mA per amplifier (30–40mA total), resulting in low self-heating. No thermal pad or heatsink is required for standard video line driver operation within industrial temperature limits.
