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.
