ADL5519ACPZ-R2

RF Misc ICS And Modules Overview

The ADL5519ACPZ-R2 is a dual-demodulating logarithmic amplifier incorporating two AD8317 channels, designed for RF signal measurement. It operates within a frequency range of 1 MHz to 10 GHz and provides a dynamic range of 62 dB (±3 dB), maintaining >50 dB with ±1 dB accuracy up to 8 GHz. The device features independent logarithmic output voltages for each channel, plus differential outputs (OUTP/OUTN) measuring the difference between channels. It includes an integrated temperature sensor and offers stability over temperature of ±0.5 dB from -40°C to +85°C. Supply voltage ranges from 3.3 V to 5.5 V at 60 mA, housed in a 5 mm × 5 mm, 32-lead LFCSP_VD package.

RF Misc ICS And Modules Procurement Notes

Verify the specific suffix R2 against official Analog Devices documentation to confirm tape-and-reel packaging configuration. Ensure the operating temperature range requirements align with the specified -40°C to +125°C limit. Confirm that the 32-lead LFCSP_VD footprint matches the PCB design constraints. Cross-reference the latest datasheet revision to validate electrical parameters such as the 62 dB dynamic range and 1 MHz to 10 GHz bandwidth specifications before finalizing procurement.

RF Misc ICS And Modules Selection Notes

Select this component when dual-channel log detection with differential output capability is required for precise RF power monitoring. The integrated temperature sensor simplifies thermal compensation in complex RF front-ends. Consider the 3.3 V to 5.5 V supply range and 60 mA current consumption for power budgeting. The SiGe process ensures high-speed performance suitable for wideband applications up to 10 GHz. Evaluate the 5 mm × 5 mm package size for space-constrained designs requiring robust channel matching stability.

RF Misc ICS And Modules Part Context

The ADL5519 belongs to Analog Devices' family of dual-demodulating logarithmic amplifiers, effectively combining two AD8317 units into a single compact package. This integration reduces board space and improves channel-to-channel matching compared to discrete solutions. The device leverages high-speed SiGe technology to achieve wide bandwidth and fast pulse response times. It serves as a versatile solution for applications requiring simultaneous amplitude measurement and differential comparison of RF signals across a broad frequency spectrum.
