AD8139ARDZ - Brand New Analog Devices Instrumentation OpAmps
-
Description
The AD8139ARDZ is an ultralow noise, high performance differential amplifier with rail-to-rail output. It is ideal for driving ADCs with resolutions to 18 bits due to its low noise, high SFDR, and wide bandwidth. 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.
