LT6553CGN#PBF

Video Amps And Modules Overview

The LT6553CGN#PBF is a high-speed triple video amplifier manufactured by Analog Devices Inc. in a 16-lead SSOP package. It features an internally fixed gain of 2, optimized for driving double-terminated 75Ω video loads. The device provides a small signal bandwidth of 650MHz and a large signal bandwidth of 400MHz at 2VP-P. It operates on dual supplies from ±2.25V to ±6V or a single supply from 4.5V to 12V. Each amplifier draws 8mA with ±5V supplies and includes a TTL-compatible enable pin that reduces current to under 100μA when disabled.

Video Amps And Modules Feature Summary

• Triple channel architecture with individually separated power supply pins to enhance channel isolation
• Internally fixed gain of 2 eliminates the need for external feedback resistors
• TTL compatible shutdown mode allows for rapid turn-on and low standby current consumption
• Optimized performance characteristics specifically designed for driving standard 75Ω coaxial video cables

Video Amps And Modules Applications

• RGB buffer circuits for display systems
• Coaxial cable drivers for video transmission
• LCD projectors requiring high-resolution signal buffering
• Video multiplexing and switching applications

Video Amps And Modules Procurement Notes

Verify the specific suffix 'GN' corresponds to the 16-lead SSOP package and commercial temperature range during sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the exact manufacturer designation to avoid compatibility issues with PCB footprints and electrical specifications.

Video Amps And Modules Selection Notes

Select this component for designs requiring high-speed amplification of RGB signals without external gain setting components. Consider the separate supply pins if maximizing channel separation is critical for the application. Evaluate the single-supply capability if the system design restricts the use of negative voltage rails.

Video Amps And Modules Part Context

This device belongs to the LT6553 series of high-speed video amplifiers. It is distinct from interface transceivers like the LTC1385 or other video switches such as the LT6555. The CGN variant specifies the commercial grade operating temperature range within the narrow SSOP package format.
