LT1253CN8#PBF

Video Amps And Modules Overview

The LT1253CN8#PBF is a low-cost dual current feedback video amplifier manufactured by Analog Devices Inc. It features a wide supply range of ±2V to ±14V and operates within an ambient temperature range of 0°C to 70°C. The device provides excellent channel isolation exceeding 94dB at 5MHz, with a typical output slew rate of 250V/µs and a bandwidth of 90MHz on ±5V supplies. Each amplifier draws 6mA of supply current, resulting in low power consumption of 60mW per amplifier at ±5V.

Video Amps And Modules Feature Summary

• Current feedback architecture optimized for driving low impedance loads such as cables and filters
• High channel isolation exceeding 94dB at 5MHz due to completely isolated internal circuitry except for power pins
• Wide supply voltage range supporting operation from ±2V to ±14V

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 specific package type matches the design requirements, as this part number denotes the 8-lead plastic DIP (N8) configuration. Confirm that the commercial temperature range of 0°C to 70°C aligns with the operational environment. Ensure the datasheet specifications for differential gain and phase are sufficient for the intended video signal integrity standards.

Video Amps And Modules Selection Notes

Select this component when cost reduction is prioritized without sacrificing high-speed video performance. The dual configuration reduces board space and bypass capacitor count compared to single amplifiers. Verify that the required bandwidth and slew rate meet the application needs, noting that higher gains may reduce the effective bandwidth.

Video Amps And Modules Part Context

This component belongs to the LT1253/LT1254 family of low-cost video amplifiers. The LT1253 is the dual version, while the LT1254 is the quad version. Both share industry-standard pinouts for dual and quad op amps, facilitating easy integration into existing designs requiring multiple video channels.

Video Amps And Modules Replacement Considerations

For higher performance requirements, consider the LT1229 or LT1230 series. Ensure any substitute maintains the current feedback topology and compatible supply voltage ranges.
