LT6558IDHC#TRPBF

Video Amps And Modules Overview

The LT6558IDHC#TRPBF is a high-speed triple video amplifier featuring an internal fixed gain of 1 and programmable DC input bias voltage. It offers 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 supports a supply range of 3V to 7.5V, with outputs swinging to within 0.8V of the rails. It includes separate power pins for each channel to minimize crosstalk and features an enable/shutdown pin. The component operates from –40°C to 85°C and is housed in a 16-lead 5mm × 3mm DFN package.

Video Amps And Modules Feature Summary

• Internal fixed gain of 1 eliminates the need for external feedback resistors
• Programmable DC input bias via a single resistor simplifies AC-coupled designs
• Separate power and ground pins per channel enhance isolation and bypassing
• Enable/shutdown control reduces power consumption during inactive periods

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 ordering suffix #TRPBF confirms the tape and reel packaging format and lead-free status. Confirm the IDHC suffix corresponds to the industrial temperature grade (-40°C to 85°C) and the specific 16-lead DFN package dimensions. Ensure compatibility with the required PCB footprint for the exposed pad thermal connection.

Video Amps And Modules Selection Notes

Select this part for applications requiring a gain of 1 without external resistors. Choose the DHC package if space constraints require a 5mm × 3mm footprint. Verify that the 2200V/µs slew rate meets the signal requirements. Consider the separate supply pins for improved channel separation in dense layouts.

Video Amps And Modules Part Context

The LT6558 belongs to Analog Devices' family of high-speed triple video amplifiers. It shares architectural similarities with the LT6554 but differs in bandwidth and specific application optimizations. Unlike the LT6557 which has a gain of 2, this model provides unity gain. It is designed for single-supply operation, contrasting with multiplexers like the LT6555.
