LT6558IGN#PBF

Video Amps And Modules Overview

The LT6558IGN#PBF is a high-speed triple video amplifier manufactured by Analog Devices Inc. It features an internal fixed gain of 1 and a programmable DC input bias voltage. Key electrical parameters include a -3dB small-signal bandwidth of 550MHz, a large-signal bandwidth of 400MHz at 2VP-P, and a slew rate of 2200V/µs. The device operates on a single supply voltage ranging from 3V to 7.5V, with a typical operating current of 22.5mA per channel. It provides full video swing with a 5V supply and can drive heavy loads to within 0.8V of the supply rails. The component is housed in a 16-lead SSOP package.

Video Amps And Modules Feature Summary

• Features a unique ability to drive heavy output loads to 0.8V of the supply rails, enabling full video swing with a single 5V supply.
• Includes a programmable DC input bias circuit that allows all three amplifier inputs to be set to a common voltage level using a single resistor.
• Provides separate power supply and ground pins for each amplifier channel to improve channel separation and simplify power supply bypassing.

Video Amps And Modules Applications

• LCD Video Projectors
• RGB HD Video Amplifiers
• Coaxial Cable Drivers

Video Amps And Modules Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing this component. Confirm the package type matches the required PCB footprint, as the LT6558 series is also available in DFN packages. Ensure the ordering part number aligns with the desired temperature grade and packaging format before finalizing procurement orders.

Video Amps And Modules Selection Notes

Select the LT6558IGN#PBF for applications requiring a fixed gain of 1 without external feedback resistors. Consider thermal management carefully, as the SSOP package has a junction-to-ambient thermal resistance of 110°C/W. Use separate ground connections for each channel to minimize crosstalk in high-frequency designs.

Video Amps And Modules Part Context

This component belongs to the LT6558 series of triple video amplifiers designed for wideband video applications. It is distinct from related parts like the LT6557 or LT6559 due to its specific combination of 550MHz bandwidth, 2200V/µs slew rate, and integrated input bias control. The series is optimized for low-voltage, single-supply operation in professional video systems.

Video Amps And Modules Replacement Considerations

LT6557IGN#PBF: Offers similar performance but with a gain of 2 instead of 1. LT6554IGN#PBF: Provides comparable 650MHz bandwidth and gain of 1 performance in the same package.
