LT6557IDHC#TRPBF

Video Amps And Modules Overview

The LT6557IDHC#TRPBF is a high-speed triple video amplifier featuring an internal fixed gain of 2 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 500MHz and a large-signal bandwidth of 400MHz at 2VP-P output. Key performance metrics include a slew rate of 2200V/µs, differential gain of 0.02%, and differential phase of 0.05°. It supports full video swing with a 5V supply and offers high output current capability of ±100mA.

Video Amps And Modules Feature Summary

• Triple video amplifier architecture with separate power supply and ground pins for each channel to minimize crosstalk.
• Internal fixed gain of 2 eliminates the need for external feedback resistors.
• Programmable DC input bias control via a single resistor simplifies AC-coupled designs.
• Enable/shutdown pin allows for low-power standby mode with reduced supply current.

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 when ordering. Confirm the IDHC package designation corresponds to the 16-lead 5mm × 3mm DFN form factor required for your PCB layout. Ensure the temperature grade matches your environmental specifications, as the 'I' variant covers the full -40°C to 85°C range.

Video Amps And Modules Selection Notes

Select this component for applications requiring high-speed signal processing with minimal external passive components. The integrated bias control reduces circuit complexity in AC-coupled systems. Consider thermal management requirements due to the high slew rate, ensuring junction temperatures remain within limits for the DFN package. Verify that the 500MHz bandwidth meets the frequency requirements of the target video signals.
