LT6554IGN#TRPBF

Video Amps And Modules Overview

The LT6554IGN#TRPBF is a high-speed triple video buffer manufactured by Analog Devices Inc. It features an internally fixed gain of 1 and operates within a supply voltage range of ±2.25V to ±6V (4.5V to 12V single supply). The device provides a small-signal bandwidth of 650MHz, a large-signal bandwidth of 400MHz at 2VP-P, and a slew rate of 2500V/µs. It draws 8mA per amplifier with a TTL-compatible enable pin that reduces current to under 100µA when disabled. Packaged in a 16-lead SSOP.

Video Amps And Modules Procurement Notes

Verify the specific suffix IGN#TRPBF against official manufacturer documentation to confirm temperature grade and packaging type. Ensure compatibility with the required operating environment and PCB footprint specifications before finalizing procurement decisions.

Video Amps And Modules Selection Notes

Select this component for applications requiring high bandwidth and low distortion in RGB signal paths. Consider the separate supply pin configuration for enhanced channel separation. Evaluate the need for series output resistance if driving significant capacitive loads to maintain frequency response stability.

Video Amps And Modules Part Context

This part belongs to the LT6554 family of high-speed video buffers. It is designed using a proprietary low-voltage complementary bipolar process. The device is available in a 16-lead SSOP package, occupying the same PCB area as an SO-8 package, facilitating compact design implementations.

Video Amps And Modules FAQ

How does the LT6554 achieve high channel separation?

The LT6554 utilizes separate power supply pins for each amplifier channel. This design boosts channel separation to 90dB at 10MHz, minimizing crosstalk between the red, green, and blue channels.

What is the function of the AGND pins?

The AGND pins provide analog ground isolation between the input stages of adjacent channels. Connecting these pins to ground or a quiet node significantly increases channel isolation.
