AD8351SCPZ-EP-R7

Overview

The AD8351SCPZ-EP-R7 is a low-cost, fully differential RF/IF amplifier manufactured by Analog Devices Inc. Designed for applications up to 2.2 GHz, this component provides a voltage gain range from unity to 26 dB, adjustable via an external resistor. It operates on a supply voltage of 3 V to 5.5 V with a typical supply current of 28 mA. Key performance metrics include a noise figure of 15.5 dB, a P1dB compression point of 13.3 dBm, and an OIP3 of 31 dBm. The device utilizes Silicon technology and is housed in a 16-LFCSP-WQ (3x3) package. It supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fully differential architecture suitable for driving high-resolution ADCs in communication transceivers
• Adjustable voltage gain ranging from unity to 26 dB using a single external resistor
• Low distortion performance optimized for RF and IF applications up to 2.2 GHz

Applications

• Driving high-resolution (10-14 bit) / high-speed ADCs at intermediate frequencies
• RF and IF amplification in wireless communication transceivers
• Signal conditioning in broadband communication systems

Procurement Notes

Verify the specific suffix 'EP' indicates enhanced product specifications or environmental compliance as defined by Analog Devices. Confirm that the LFCSP-WQ package matches your PCB footprint requirements. Check current availability status as distribution channels may report limited stock or restricted supply conditions. Ensure the operating temperature range aligns with your system's thermal design constraints before finalizing procurement.

Selection Notes

Select this component when a fully differential output is required to drive subsequent stages such as ADCs or mixers. The adjustable gain feature allows flexibility in system design without changing internal components. Consider the 2.2 GHz frequency limit and 28 mA supply current when designing power and signal integrity paths. Verify that the 16-pin LFCSP package fits within the available board space and thermal dissipation capabilities of the application.

Part Context

The AD8351 series consists of low-cost differential amplifiers intended for RF and IF applications. The AD8351ACPZ-R7 variant shares similar electrical characteristics but differs in packaging and potentially qualification levels. The AD8351SCPZ-EP-R7 specifically denotes the commercial grade part in the LFCSP package with enhanced product attributes. This family simplifies ADC driver circuits by providing balanced outputs and easy gain configuration.

Replacement Considerations

The AD8351ACPZ-R7 is a related variant within the same product family. Verify if the ACPZ package type meets mechanical constraints if replacing the SCPZ version. No other direct substitute part numbers are confirmed in the provided documentation.
