LT5524EFE#PBF

Overview

The LT5524EFE#PBF 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 features digitally controlled gain, offering a nominal gain of 27 dB. The device requires a supply voltage between 4.75 V and 5.25 V with a typical operating current of 75 mA. 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 20-lead TSSOP package and supports operation from -40°C to +85°C.

Feature Summary

• Digitally controlled variable gain architecture for precise signal adjustment
• Low distortion characteristics optimized for intermediate frequency applications
• Integrated design serving as both an IF amplifier and ADC driver

Applications

• Intermediate frequency amplification in communication systems
• Driving analog-to-digital converters in receiver front-ends
• Wireless infrastructure signal processing

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliance when sourcing. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the digital control interface logic levels are compatible with your system controller. Check for any recent product change notices regarding manufacturing site or material composition updates from Analog Devices.

Selection Notes

Select this component when a combined IF amplifier and ADC driver solution is required to minimize board space. Consider the 27 dB gain and 8.6 dB noise figure for sensitivity requirements. Evaluate the 40 dBm OIP3 against linearity needs in high-interference environments. Verify that the 5V supply rail and 75 mA current consumption fit your power budget constraints.
