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 internal 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  
outstanding 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  
four resistors determine the closed-loop gain of the amplifier.

The AD8139 is manufactured on the Analog Devices, Inc.  
proprietary, second-generation XFCB process, enabling it to  
achieve low levels of distortion with input voltage noise of only  
2.25 nV/√Hz.
