AD8350AR15

Overview

The AD8350AR15 is a high-performance fully-differential amplifier from Analog Devices, designed for RF and IF circuits up to 1000 MHz. It features a low noise figure of 5.9 dB at 250 MHz and an output third-order intercept point (OIP3) of +28 dBm at 250 MHz with a 50 Ω load. The device offers a fixed gain of 15 dB and operates on a single supply voltage ranging from 5 V to 10 V, drawing 28 mA of supply current. It provides a -3 dB bandwidth of 1.0 GHz and maintains input/output impedance at 200 Ω. Available in 8-lead SOIC packages, it supports both single-ended and differential input drive configurations.

Feature Summary

• High dynamic range with exceptional linearity and increased common-mode rejection
• Low noise figure performance suitable for sensitive signal chains
• Capable of functioning as a general-purpose gain block or A-to-D driver
• Supports single-ended-to-differential conversion functionality

Applications

• Cellular base stations
• Communications receivers
• RF/IF gain blocks
• Differential A-to-D drivers
• Single-ended-to-differential conversion

Procurement Notes

Verify the specific suffix AR15 confirms the 15 dB gain variant when sourcing. Confirm package type matches design requirements, as the series includes microSOIC options. Check RoHS compliance status via official documentation. Ensure supply chain sources are authorized to guarantee component authenticity and traceability for critical RF applications.

Selection Notes

Select this model for designs requiring a fixed 15 dB gain in differential signal paths. Consider the AD8350AR20 if a 20 dB gain configuration is preferred. Evaluate the 1.0 GHz bandwidth against system frequency needs. Verify power supply constraints align with the 5 V to 10 V operating range. Assess thermal management requirements based on the 28 mA supply current draw.

Part Context

The AD8350 series comprises high-performance fully-differential amplifiers intended for demanding communications transceiver applications. This family enables high dynamic range differential signal chains with excellent linearity. The AD8350AR15 specifically denotes the 15 dB gain version within this lineup, offering robust performance for RF and IF stages up to 1000 MHz.

Replacement Considerations

The AD8350AR20 serves as a direct functional substitute within the same series, differing only by providing 20 dB gain instead of 15 dB. Both share identical pinouts, packaging options, and electrical characteristics except for the gain setting.
