MAX4310EUA+

Video Amps And Modules Overview

The MAX4310EUA+ is a high-speed, low-power video multiplexer-amplifier from Analog Devices/Maxim Integrated. It integrates a 2-channel analog multiplexer with an adjustable-gain 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 rail-to-rail outputs and an input common-mode range extending to the negative rail. The device offers a -3dB bandwidth of 280MHz, a slew rate of 460V/µs, and a quiescent current of 6.1mA. It is housed in an 8-pin µMAX package and operates within a temperature range of -40°C to +85°C.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference pin configurations with the official application notes to ensure compatibility with existing board layouts and power-supply bypassing requirements.

Video Amps And Modules Selection Notes

Select this component for applications requiring high-speed video switching with minimal signal distortion. The adjustable gain configuration suits designs needing flexibility around unity gain. Consider the low-power shutdown feature for battery-operated systems. Ensure layout guidelines are followed to maintain the specified bandwidth and stability characteristics under capacitive loads.

Video Amps And Modules Part Context

This device belongs to the MAX4310–MAX4315 family of single-supply mux-amps. While other family members offer different channel counts (4 or 8) or fixed gains (+2V/V), the MAX4310 specifically provides two channels with adjustable gain. This makes it distinct from the MAX4313, which has two channels but a fixed +2V/V gain optimized for back-terminated cables.

Video Amps And Modules Replacement Considerations

The MAX4310ESA is an alternative part number within the same family offering identical electrical specifications but utilizing an 8-pin SO package instead of the µMAX format. Designers must verify footprint compatibility when substituting between these package options.

Video Amps And Modules FAQ

How does the MAX4310 handle capacitive loads?

Driving highly capacitive loads can decrease phase margin and cause instability. The datasheet recommends using an isolation resistor (RISO) between the output and the load to maintain stability, with optimal resistance values depending on the specific capacitance.

What is the input common-mode voltage range?

The input common-mode range extends from the negative supply rail (VEE) to VCC minus approximately 2.7V. This allows the device to sense signals down to ground in single-supply applications.
