AD8350AR20

Overview

The AD8350AR20 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 -3 dB bandwidth of 1.0 GHz, and an output third-order intercept point (OIP3) of +28 dBm at 250 MHz. The device operates on a single supply voltage ranging from 5 V to 10 V with a typical supply current of 28 mA. It offers a low noise figure of 5.9 dB at 250 MHz and supports both single-ended and differential input drive configurations.

Feature Summary

• Provides high dynamic range with exceptional linearity and increased common-mode rejection for signal integrity.
• Supports versatile signal conversion functions including single-ended-to-differential conversion and A-to-D driving.
• Operates efficiently on a single power supply, simplifying circuit design for communications transceivers.

Applications

• Cellular Base Stations
• Communications Receivers
• RF/IF Gain Block
• Differential A-to-D Driver
• High Speed Data Transmission

Procurement Notes

Verify the specific suffix AR20 against official Analog Devices documentation to confirm the 20 dB gain variant and SOIC package configuration. Ensure compatibility with the required 5 V to 10 V single-supply operation and 28 mA current consumption. Confirm that the 1.0 GHz bandwidth and +28 dBm OIP3 meet the system's RF and IF performance requirements before integration.

Selection Notes

Select this component when a fixed 20 dB gain is required for RF or IF stages up to 1 GHz. It is suitable for applications demanding low noise figures around 5.9 dB and high linearity indicated by a +28 dBm OIP3. Consider its capability as a general-purpose gain block or A-to-D driver where single-ended inputs must be converted to differential signals for downstream processing.

Part Context

The AD8350 series comprises high-performance fully-differential amplifiers tailored for demanding communications transceiver applications. The AD8350AR20 specifically denotes the 20 dB gain version housed in an 8-lead SOIC package. This series enables high dynamic range differential signal chains, offering excellent noise performance and linearity essential for modern wireless infrastructure.

Replacement Considerations

The AD8350ARMZ20 serves as a pin-compatible alternative featuring the same 20 dB gain but packaged in a microSOIC format. Verify package dimensions and thermal characteristics when substituting between SOIC and microSOIC variants.
