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-
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.
