AD8139ARDZ

The AD8139ARDZ is a Low Noise Rail-to-rail Differential ADC Driver ideal choice for driving ADCs with resolutions to 18-bits. It 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. Simple external feedback networks consisting of four resistors determine the closed-loop gain of the amplifier. This ADC driver is manufactured on proprietary, second-generation XFCB process, enabling it to achieve low levels of distortion with input voltage noise of only 2.25nV/?Hz.
