MAX4311ESD

Video Amps And Modules Overview

The MAX4311ESD is a high-speed, low-power video multiplexer-amplifier from the MAX4310–MAX4315 family. It integrates a 4-channel analog multiplexer with an adjustable-gain output amplifier optimized for unity-gain stability. Operating from a single +4V to +10.5V supply or dual supplies of ±2V to ±5.25V, it features a 345MHz -3dB bandwidth and up to 430V/µs slew rate. The device offers 40ns channel switching time, ultra-low 10mVp-p switching transients, and rail-to-rail outputs in a 14-pin Narrow SO package.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'ESD' corresponds to the 14-pin Narrow SO package and -40°C to +85°C temperature range. Confirm that the component meets all required electrical specifications for your application before finalizing procurement decisions.

Video Amps And Modules Selection Notes

Select this part when four input channels are required with flexible gain settings. Choose the MAX4311 over fixed-gain variants like the MAX4314 if unity-gain stability is preferred. Ensure the design accommodates the 14-pin Narrow SO footprint and operates within the specified voltage and temperature limits.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 series of single-supply mux-amps. The family differentiates devices by the number of multiplexer inputs (2, 4, or 8) and the amplifier gain configuration (adjustable or fixed +2V/V). The MAX4311 specifically provides the 4-channel option with adjustable gain.

Video Amps And Modules Replacement Considerations

The MAX4314ESD serves as a functional substitute if a fixed +2V/V gain is acceptable instead of adjustable gain. Other family members like the MAX4310 or MAX4312 differ in channel count and must be evaluated for pin compatibility and performance requirements.

Video Amps And Modules FAQ

What is the quiescent supply current in normal operation?

The quiescent supply current is typically 6.9mA.

How does the device handle capacitive loads?

An isolation resistor can be used between the output and the load to maintain stability when driving high-capacitive loads.
