PRODUCT DESCRIPTION

The AD8350 series are high performance fully-differential

amplifiers useful in RF and IF circuits up to 1000 MHz. The

amplifier has excellent noise figure of 5.9 dB at 250 MHz. It

offers a high output third order intercept (OIP3) of +28 dBm

at 250 MHz. Gain versions of 15 dB and 20 dB are offered.

The AD8350 is designed to meet the demanding performance

requirements of communications transceiver applications. It

enables a high dynamic range differential signal chain, with

exceptional linearity and increased common-mode rejection.

The device can be used as a general purpose gain block, an

A-to-D driver, and high speed data interface driver, among

other functions. The AD8350 input can also be used as a single-

ended-to-differential converter.

The amplifier can be operated down to 5 V with an OIP3 of

+28 dBm at 250 MHz and slightly reduced distortion perfor-

mance. The wide bandwidth, high dynamic range and temperature

stability make this product ideal for the various RF and IF

frequencies required in cellular, CATV, broadband, instrumen-

tation and other applications.

The AD8350 is offered in an 8-lead single SOIC package and

µSOIC package. It operates from 5 V and 10 V power supplies,

drawing 28 mA typical. The AD8350 offers a power enable func-

tion for power-sensitive applications. The AD8350 is fabricated

using Analog Devices’ proprietary high speed complementary

bipolar process. The device is available in the industrial (–40

°C to

+85

°C) temperature range.
