AD8350ARM20-REEL7

低失真1.0 GHz差分放大器 Low Distortion 1.0 GHz Differential Amplifier

Product Details

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 performance. 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, instrumentation 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 function 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.
