The amplifier can be operated down to 5 V with an OIP3 of The AD8350 series are high performance fully-differential +28 dBm at 250 MHz and slightly reduced distortion perfor- amplifiers useful in RF and IF circuits up to 1000 MHz. The mance. The wide bandwidth, high dynamic range and temperature amplifier has excellent noise figure of 5.9 dB at 250 MHz. It stability make this product ideal for the various RF and IF offers a high output third order intercept (OIP3) of +28 dBm frequencies required in cellular, CATV, broadband, instrumen- at 250 MHz. Gain versions of 15 dB and 20 dB are offered. tation and other applications. The AD8350 is designed to meet the demanding performance The AD8350 is offered in an 8-lead single SOIC package and requirements of communications transceiver applications. It μSOIC package. It operates from 5 V and 10 V power supplies, enables a high dynamic range differential signal chain, with drawing 28 mA typical. The AD8350 offers a power enable func- exceptional linearity and increased common-mode rejection. tion for power-sensitive applications. The AD8350 is fabricated The device can be used as a general purpose gain block, an using Analog Devices’ proprietary high speed complementary A-to-D driver, and high speed data interface driver, among bipolar process. The device is available in the industrial (–40°C to other functions. The AD8350 input can also be used as a single- +85°C) temperature range. ended-to-differential converter.
