LT6558IGN#TRPBF

Video Amps And Modules Overview

The LT6558IGN#TRPBF is a high-speed triple video amplifier from Analog Devices, featuring an internal fixed gain of 1 and programmable DC input bias voltage. It operates on a single supply ranging from 3V to 7.5V, with a typical operating current of 22.5mA per channel. The device provides a –3dB small-signal bandwidth of 550MHz and a large-signal bandwidth of 400MHz at 2VP-P. Key performance metrics include a slew rate of 2200V/µs, output swing within 0.8V of the supply rails, and high output current capability of ±90mA. It is housed in a 16-lead SSOP package.

Video Amps And Modules Feature Summary

• Features separate power supply and ground pins for each amplifier channel to improve channel separation and simplify bypassing.
• Includes a unique programmable DC input bias circuit that allows AC coupling with a single external resistor.
• Capable of driving heavy loads with full video swing when operated from a standard 5V single supply.
• Provides an enable/shutdown pin to deactivate all three channels, reducing supply current significantly.

Video Amps And Modules Applications

• LCD Video Projectors
• RGB HD Video Amplifiers
• Coaxial Cable Drivers
• Low Supply ADC Drivers

Video Amps And Modules Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the IGN designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure the 16-lead SSOP package matches your PCB footprint requirements. Cross-reference the datasheet revision date to confirm electrical characteristics remain unchanged.

Video Amps And Modules Selection Notes

Select this component for applications requiring a single-supply, triple-channel video amplifier with high slew rates. It is suitable where differential gain and phase errors must be minimized, such as in professional video equipment. Consider the thermal dissipation limits of the SSOP package if operating near maximum supply voltages or temperatures.

Video Amps And Modules Part Context

This part belongs to the LT6558 series of high-speed video amplifiers. It shares architectural similarities with other members like the LT6554 and LT6557 but is distinct in its specific bandwidth and gain configuration. The series is designed for wideband video applications requiring precise signal integrity and low distortion.

Video Amps And Modules Replacement Considerations

LT6554IGN#PBF offers similar gain of 1 performance in the same package family. LT6557IGN#PBF provides higher bandwidth (500MHz) and gain of 2. Verify pin compatibility and thermal requirements before substitution.
