LT6557CDHC#PBF

Video Amps And Modules Overview

The LT6557CDHC#PBF is a high-speed triple video amplifier featuring an internal fixed gain of 2 and programmable DC input bias voltage. It offers a –3dB small-signal bandwidth of 500MHz and a large-signal bandwidth of 400MHz at 2VP-P, with a slew rate of 2200V/µs. The device supports a supply range of 3V to 7.5V and operates from –40°C to 85°C. It provides full video swing with a single 5V supply, output swings to within 0.8V of the rails, and delivers ±100mA output current. Differential gain is 0.02% and differential phase is 0.05°.

Video Amps And Modules Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging when ordering. Confirm the DHC package variant matches the required footprint. Ensure the temperature grade 'C' meets the operational requirements of the target environment. Cross-reference the datasheet revision to confirm electrical characteristics align with the design specifications.

Video Amps And Modules Selection Notes

Select this component for wideband video applications requiring high slew rates and precise gain matching. The separate supply and ground pins minimize crosstalk between channels. Consider thermal management for the DFN package, as junction temperature limits are lower than the SSOP variant. Use the programmable bias feature to simplify AC-coupling designs.

Video Amps And Modules Part Context

This part belongs to the LT6557 series of triple video amplifiers. It is available in 16-lead SSOP and 5mm × 3mm DFN packages. The CDHC variant specifies the commercial temperature range and DFN package. Related parts include the LT6553 and LT6554, which offer similar performance with different gain configurations or multiplexer functions.

Video Amps And Modules Replacement Considerations

LT6557IDHC#PBF offers the same electrical performance but with an extended industrial temperature range (-40°C to 85°C guaranteed). LT6557CGN#PBF is the SSOP package equivalent. Verify pinout compatibility and thermal dissipation requirements when substituting.
