LT5524EFE#TRPBF

Overview

The LT5524EFE#TRPBF is a low distortion intermediate frequency amplifier and ADC driver manufactured by Analog Devices Inc. It operates within a frequency range up to 540 MHz and provides a gain of 27 dB. The device functions on a supply voltage between 4.75 V and 5.25 V, drawing 75 mA of current. Key performance metrics include a noise figure of 8.6 dB and an output third-order intercept point (OIP3) of 40 dBm at a test frequency of 100 MHz. It is housed in a TSSOP-20 surface-mount package and supports digital control for variable gain adjustment.

Feature Summary

• Digitally controlled variable gain functionality
• Low distortion intermediate frequency amplification
• Integrated analog-to-digital converter driver capability

Applications

• Intermediate frequency signal processing
• Direct sampling receiver architectures
• Wireless communication systems requiring ADC interfacing

Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging distinct from the tube variant. Confirm RoHS compliance status through official documentation. Ensure the component source is authorized to prevent counterfeit risks. Validate that the specific reel quantity matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when digital gain control is required for IF signals near 540 MHz. Consider the 8.6 dB noise figure and 40 dBm OIP3 for linearity needs. The TSSOP-20 package suits space-constrained designs. Verify compatibility with the target ADC input specifications regarding voltage levels and drive requirements.
