LT1254CN#PBF

Video Amps And Modules Overview

The LT1254CN#PBF is a quad current feedback video amplifier manufactured by Analog Devices Inc. It operates on a wide supply range of ±2V to ±14V and delivers a bandwidth of 90MHz at ±5V with a flat response to 30MHz (0.1dB). Key electrical parameters include a differential gain of 0.03% and differential phase of 0.28° at RL = 150Ω, VS = ±5V. The device features an input slew rate of 125V/μs and output slew rate of 250V/μs. Power consumption is low at 60mW per amplifier at ±5V. It is housed in a 14-lead plastic DIP package.

Video Amps And Modules Feature Summary

• Provides excellent channel isolation exceeding 94dB at 5MHz for multi-channel applications
• Capable of driving low impedance loads such as cables and filters efficiently
• Offers high linearity suitable for composite video signal processing

Video Amps And Modules Applications

• RGB cable drivers for PCs and workstations
• Composite video cable drivers
• Gain blocks in IF stages

Video Amps And Modules Procurement Notes

Verify the component matches the specific LT1254CN#PBF designation from Analog Devices Inc. Ensure the datasheet confirms the 14-lead plastic DIP package and commercial temperature range. Confirm that the #PBF suffix indicates lead-free compliance if required by your assembly specifications.

Video Amps And Modules Selection Notes

Select this part when multiple isolated video channels are needed within a single package to reduce board space and bypass capacitor count. It is suitable for applications requiring high slew rates and wide bandwidth to drive low impedance loads like 75Ω or 150Ω cables without significant signal degradation.

Video Amps And Modules Part Context

The LT1254 is the quad version of the LT1253 dual video amplifier. Both share identical pinouts for their respective channel counts and utilize industry-standard op amp configurations. They are designed to lower costs compared to using individual single amplifiers while maintaining high performance metrics for video signal integrity.

Video Amps And Modules Replacement Considerations

For higher performance requirements, consider the LT1229 or LT1230 series. Verify compatibility regarding supply voltage ranges and thermal dissipation characteristics when substituting.
