MAX4315ESE

Video Amps And Modules Overview

The MAX4315ESE is a high-speed, low-power video multiplexer-amplifier from Analog Devices Inc./Maxim Integrated. It integrates an 8-channel multiplexer with a fixed +2V/V gain amplifier in a 16-pin Narrow SO package. Operating from a single +4V to +10.5V supply or dual ±2V to ±5.25V supplies, it features rail-to-rail outputs and a -40°C to +85°C operating temperature range. The device offers 97MHz bandwidth, 310V/µs slew rate, and ultra-low switching transients of 10mVp-p.

Video Amps And Modules Feature Summary

• Integrates 8-channel multiplexer with fixed +2V/V gain amplifier
• Ultra-low 10mVp-p switching transients for clean signal routing
• Rail-to-rail output capability driving loads down to 730mV of rails
• Low-power shutdown mode reduces current to 560µA

Video Amps And Modules Applications

• Video signal multiplexing
• Video crosspoint switching
• Flash ADC input buffering
• 75Ω video cable driving
• Broadcast video systems

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'ESE' corresponds to the 16-pin Narrow SO package and industrial temperature range (-40°C to +85°C). Confirm availability status directly with the manufacturer or authorized distributors as stock levels fluctuate. Ensure pinout compatibility with existing PCB layouts before procurement.

Video Amps And Modules Selection Notes

Select this part when eight video channels require simultaneous switching with precise gain control. The fixed +2V/V gain makes it suitable for driving back-terminated cables where signal amplification is necessary. Compare against MAX4310-MAX4314 if different channel counts or adjustable gain configurations are required for the design.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 family of single-supply mux-amps. These devices combine high-speed operation with excellent video specifications. The family is differentiated by the number of multiplexer inputs (2, 4, or 8) and the amplifier gain configuration (adjustable or fixed +2V/V).

Video Amps And Modules Replacement Considerations

Official substitutes within the same family include MAX4315EEE (16-pin QSOP package) for identical electrical performance in a different footprint. Other family members like MAX4313ESA or MAX4314ESD offer different channel counts or gain settings but share similar operational characteristics.

Video Amps And Modules FAQ

What is the quiescent supply current in normal operation?

The quiescent supply current is typically 7.4mA to 9.4mA depending on the specific device variant within the family, with the MAX4315 drawing up to 9.4mA.

How does the device 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.
