MAX4312EEE+T

Video Amps And Modules Overview

The MAX4312EEE+T is a high-speed, low-power video multiplexer-amplifier from Analog Devices. It integrates an 8-channel analog multiplexer with an adjustable gain amplifier optimized for unity-gain stability. Operating on a single +4V to +10.5V supply, it features a 265MHz -3dB bandwidth and up to 345V/µs slew rate. The device offers 40ns channel switching time, ultra-low 10mVp-p switching transients, and rail-to-rail outputs. It includes a low-power shutdown mode reducing current to 560µA and operates within a -40°C to +85°C temperature range in a 16-pin QSOP package.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm tape-and-reel packaging and exact electrical characteristics. Confirm availability status directly with authorized distributors as supply conditions may vary. Ensure the selected component matches the required pinout and thermal specifications for the intended application environment.

Video Amps And Modules Selection Notes

Select this device when an 8-channel video switching solution with adjustable gain is required. It is suitable for applications demanding high bandwidth and minimal switching artifacts. Consider the fixed-gain MAX4315 variant if driving back-terminated cables is the primary objective instead of adjustable gain configurations.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 family of high-speed, low-power, single-supply multichannel video multiplexer-amplifiers. The family differentiates models by the number of multiplexer inputs and the amplifier gain configuration. The MAX4312 specifically combines eight channels with an adjustable gain amplifier, distinguishing it from the fixed-gain variants in the series.

Video Amps And Modules Replacement Considerations

Official substitutes within the same family include the MAX4312ESE for surface-mount SOIC packaging or the MAX4315EEE+ for a fixed +2V/V gain configuration with identical channel count. Verify pin compatibility and gain requirements before substitution.

Video Amps And Modules FAQ

What is the quiescent supply current in normal operation?

The quiescent supply current is typically 7.4mA for the MAX4312.

How does the device handle capacitive loads?

For high-capacitive loads, an isolation resistor should be used between the output and the load to maintain stability and prevent peaking in the frequency response.
