AD8350ARM20

Overview

The AD8350ARM20 is a high-performance fully-differential amplifier from Analog Devices, designed for RF and IF circuits up to 1000 MHz. It features a fixed gain of 20 dB, a gain bandwidth product of 1 GHz, and a slew rate of 2000 V/us. The device operates on a supply voltage ranging from 5 V to 10 V with a typical operating current of 28 mA. Key electrical specifications include an input bias current of 15 uA, an input offset voltage of 1 mV, and a common-mode rejection ratio of -67 dB. It is housed in an MSOP-8 surface-mount package and functions within a temperature range of -40 C to +85 C.

Feature Summary

• Provides fully differential signal amplification suitable for high-frequency applications.
• Maintains low distortion characteristics optimized for radio frequency environments.
• Delivers a fixed internal gain setting to simplify circuit design.

Applications

• RF front-end stages in communication systems
• Intermediate frequency (IF) processing circuits
• High-speed data acquisition interfaces

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to ensure correct packaging and variant selection. Confirm that the MSOP-8 package matches your board layout requirements. Check for any recent Product Change Notices regarding manufacturing updates. Ensure compatibility with your intended operating temperature range before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 20 dB gain is required for differential signaling in frequencies approaching 1 GHz. Consider the 15 uA input bias current and 1 mV offset voltage for precision requirements. Evaluate the 28 mA supply current against power constraints. The MSOP-8 package size should be verified against available PCB real estate.
