LT6557CGN#PBF

Video Amps And Modules Overview

The LT6557CGN#PBF 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 supply current of 22.5mA per amplifier. The device provides a –3dB small-signal bandwidth of 500MHz and a large-signal bandwidth of 400MHz at 2VP-P. Key performance metrics include a slew rate of 2200V/µs, differential gain of 0.02%, and differential phase of 0.05°. It supports output swings to within 0.8V of the supply rails and delivers ±100mA output current. The component is housed in a 16-lead SSOP package.

Video Amps And Modules Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the GN package designation corresponds to the 16-lead plastic SSOP form factor required for your PCB layout. Ensure the C grade temperature range meets your operational environment specifications before finalizing procurement.

Video Amps And Modules Selection Notes

Select this component for wideband video applications requiring a single 5V supply. The integrated bias control simplifies AC coupling designs by reducing external component count. Consider thermal management requirements due to high slew rates; ensure junction temperatures remain below 150°C for the SSOP package during operation.

Video Amps And Modules Part Context

This part belongs to the LT6557 family of high-speed triple video amplifiers. It is designed for low-voltage, single-supply applications where uncompromised performance is critical. The family includes variants with different packages and temperature grades, such as the DFN option.

Video Amps And Modules Replacement Considerations
