AD8139ARDZ-REEL7 General Description

The AD8139 is an ultralow noise, high performance differentialamplifier with rail-to-rail output. With its low noise, highSFDR, and wide bandwidth, it is an ideal choice for drivinganalog-to-digital converters (ADCs) with resolutions to 18 bits.The AD8139 is easy to apply, and its internal common-modefeedback architecture allows its output common-mode voltageto be controlled by the voltage applied to one pin. The internalfeedback loop also provides outstanding output balance as wellas suppression of even-order harmonic distortion products. Fullydifferential and single-ended-to-differential gain configurationsare easily realized by the AD8139. Simple external feedbacknetworks consisting of four resistors determine the closed-loopgain of the amplifier.
