General Description
AD8139 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 amplifiers closed-loop gain.
The AD8139 is manufactured on ADIs 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.
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 o +125.
