GENERAL DESCRIPTION
The AD8351 is a low cost differential amplifier useful in RF and
IF applications up to 2.2 GHz. The voltage gain can be set from
unity to 26 dB using a single external gain resistor. The AD8351
provides a nominal 150
differential output impedance. The
excellent distortion performance and low noise characteristics of
this device allow for a wide range of applications.
The AD8351 is designed to satisfy the demanding performance
requirements of communications transceiver applications. The
device can be used as a general-purpose gain block, an ADC driver,

and a high speed data interface driver, among other functions. The
AD8351 can also be used as a single-ended-to-differential
amplifier with similar distortion products as in the differential
configuration. The exceptionally good distortion performance
makes the AD8351 an ideal solution for 12-bit and 14-bit IF
sampling receiver designs.
Fabricated in ADI’s high speed XFCB process, the AD8351
has high bandwidth that provides high frequency performance
and low distortion. The quiescent current of the AD8351 is 28 mA
typically. The AD8351 amplifier comes in a compact 10-lead
MSOP package and will operate over the temperature range
of –40
