The AD8350 series are high performance fully-differentialamplifiers useful in RF and IF circuits up to 1000 MHz. Theamplifier has excellent noise figure of 5.9 dB at 250 MHz. Itoffers a high output third order intercept (OIP3) of +28 dBmat 250 MHz. Gain versions of 15 dB and 20 dB are offered.

The AD8350 is designed to meet the demanding performancerequirements of communications transceiver applications. Itenables a high dynamic range differential signal chain, withexceptional linearity and increased common-mode rejection.The device can be used as a general purpose gain block, anA-to-D driver, and high speed data interface driver, amongother functions. The AD8350 input can also be used as a single-ended-to-differentialconverter.

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 temperaturestability make this product ideal for the various RF and IFfrequencies required in cellular, CATV, broadband, instrumentationand other applications.

The AD8350 is offered in an 8-lead single SOIC package andμSOIC package. It operates from 5 V and 10 V power supplies,drawing 28 mA typical. The AD8350 offers a power enable functionfor power-sensitive applications. The AD8350 is fabricatedusing Analog Devices’ proprietary high speed complementarybipolar process. The device is available in the industrial (–40°C to+85°C) temperature range.
