Product Details

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 analog-to-digital converters 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 proprietary Analog Devices, Inc., second-generation XFCB process, enabling it to achieve low levels of distortion with input voltage noise of only 2.25 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°C to +125°C.
