MAX4312GEE+B5C

Video Amps And Modules Overview

The MAX4312GEE+B5C is a high-speed, low-power video multiplexer-amplifier integrating an 8-channel analog switch with an adjustable gain amplifier. It operates from a single +4V to +10.5V supply or dual ±2V to ±5.25V supplies. The device features a 265MHz -3dB bandwidth and up to 345V/µs slew rate. It offers 40ns channel switching time with ultra-low 10mVp-p switching transients. Quiescent current is 7.4mA typical, reducing to 560µA in shutdown mode. It provides rail-to-rail outputs and input common-mode range including the negative rail.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact package type and temperature range specifications. Ensure compatibility with required supply voltages and logic levels before integration into the design.

Video Amps And Modules Selection Notes

Select this component for applications requiring high channel count multiplexing with integrated amplification. Consider the 265MHz bandwidth and 345V/µs slew rate for high-frequency video signals. Evaluate the need for adjustable gain versus fixed gain alternatives based on system requirements.

Video Amps And Modules Part Context

This part belongs to the MAX4310–MAX4315 family of single-supply mux-amps. The family differentiates products by the number of multiplexer inputs and gain configuration. The MAX4312 specifically integrates 8-channel multiplexers with an adjustable gain amplifier, distinguishing it from fixed-gain variants in the series.

Video Amps And Modules Replacement Considerations

Consider MAX4310EUA, MAX4311EEE, MAX4313ESA, MAX4314ESE, or MAX4315EEE as pin-compatible alternatives within the same family offering different channel counts or fixed gain configurations.

Video Amps And Modules FAQ

What is the quiescent supply current for the MAX4312?

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

How does the MAX4312 handle capacitive loads?

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