Available in small SOIC package

The AD8139 is available in an 8-lead SOIC package with an

exposed paddle (EP) on the underside of its body and a 3 mm ×

3 mm LFCSP. It is rated to operate over the temperature range

of −40°C to +125°C.

GENERAL DESCRIPTION

The AD8139 is an ultralow noise, high performance differential

amplifier with rail-to-rail output. With its low noise, high SFDR,

and wide bandwidth, it is an ideal choice for driving ADCs with

resolutions to 18 bits. The AD8139 is easy to apply, and its in-

ternal common-mode feedback architecture allows its output

common-mode voltage to be controlled by the voltage applied

to one pin. The internal feedback loop also provides out-

standing output balance as well as suppression of even-order

harmonic distortion products. Fully differential and single-

ended-to-differential gain configurations are easily realized by

the AD8139. Simple external feedback networks consisting of a

total of four resistors determine the amplifier’s closed-loop gain.

100

The AD8139 is manufactured on ADI’s proprietary second gen-

eration XFCB process, enabling it to achieve low levels of distor-

tion with input voltage noise of only 1.85 nV/√Hz.
