LT6558CDHC#PBF

Video Amps And Modules Overview

The LT6558CDHC#PBF is a high-speed triple video amplifier with an internal fixed gain of 1 and programmable DC input bias voltage. It features a 400MHz large-signal bandwidth, 2200V/µs slew rate, and ±90mA output current. The device operates on a single supply from 3V to 7.5V, providing full video swing with a 5V source. It includes separate power pins for each channel to improve isolation and supports AC coupling via a single external resistor.

Video Amps And Modules Feature Summary

• Triple-channel architecture with independent power and ground pins per amplifier to minimize crosstalk
• Programmable DC input bias circuitry simplifies AC-coupled designs by eliminating the need for external clamping circuits
• Integrated enable/shutdown control pin allows for low-power standby modes
• Capable of driving heavy loads with output swings extending to within 0.8V of the supply rails

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 that the specific suffix #PBF confirms lead-free compliance and RoHS standards as required by your manufacturing specifications. Confirm the DFN-16 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental constraints. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Video Amps And Modules Selection Notes

Select this component when a fixed unity gain configuration is required for RGB signal processing. The integrated bias control reduces external component count compared to standard video amplifiers. Consider the thermal dissipation characteristics of the DFN package if operating near maximum supply voltages or temperatures. Verify that the 550MHz small-signal bandwidth satisfies the highest frequency components of the video signal.

Video Amps And Modules Part Context

This device belongs to the LT6558 series of single-supply triple video amplifiers. It shares architectural similarities with the LT6557 but differs in its fixed gain setting of 1 versus 2. The CDHC variant specifically denotes the commercial temperature grade housed in the 5mm x 3mm DFN package. It is designed for applications requiring high linearity and fast transient response in compact form factors.

Video Amps And Modules Replacement Considerations

LT6554CDHC#PBF offers similar performance with a gain of 1 but may have different thermal characteristics.
