LT6558IDHC#PBF

Video Amps And Modules Overview

The LT6558IDHC#PBF is a high-speed triple video amplifier housed in a 16-lead 5mm × 3mm DFN package. It features a fixed gain of 1 and a programmable DC input bias voltage via the BCV pin. Key electrical specifications 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 ranging from 3V to 7.5V, with typical operation at 5V. It supports output swings to within 0.8V of the supply rails and provides an enable/shutdown function. Differential gain and phase are specified at 0.02% and 0.02° respectively for NTSC signals.

Video Amps And Modules Feature Summary

• Triple amplifier architecture with separate power and ground pins for each channel to minimize crosstalk and simplify bypassing.
• Internal fixed gain of 1 eliminates the need for external feedback resistors.
• Programmable DC input bias circuitry allows AC coupling with a single external resistor or direct coupling when disabled.
• Dedicated enable/shutdown pin reduces total supply current to approximately 10µA in shutdown mode.

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 #PBF indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the IDHC package designation corresponds to the 16-lead 5mm × 3mm DFN form factor. Ensure the temperature grade 'I' matches the required operating range of –40°C to 85°C. Cross-reference the ordering part number with official distributor catalogs to confirm availability and authenticity before procurement.

Video Amps And Modules Selection Notes

Select this component for applications requiring high-speed signal processing with minimal external component count due to the fixed gain configuration. The wide supply voltage range accommodates various system architectures, while the separate grounding scheme aids in maintaining signal integrity in dense PCB layouts. Consider thermal management requirements given the junction temperature limits of 125°C for the DFN package under high load conditions.

Video Amps And Modules Part Context

This part belongs to Analog Devices' family of high-speed video amplifiers designed for single-supply operation. It shares architectural similarities with other models like the LT6554 but offers specific performance characteristics tailored for RGB signal handling. The DFN package provides a compact footprint suitable for space-constrained portable and professional video equipment designs.

Video Amps And Modules Replacement Considerations

Public confirmed substitutes include the LT6554CDHC#PBF, which offers similar gain of 1 performance in the same package. For applications requiring higher gain, the LT6557IDHC#PBF provides a gain of 2 with comparable bandwidth. Verify pin compatibility and thermal characteristics when substituting within the LT655x series.
