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. The AD8139 is manufactured on the proprietary Analog Devices,Inc., second-generation XFCB process, enabling it to achieve lowlevels of distortion with input voltage noise of only 2.25 nV/√Hz.The AD8139 is available in an 8-lead SOIC package with anexposed paddle (EP) on the underside of its body and a 3 mm ×3 mm LFCSP. It is rated to operate over the temperature rangeof −40°C to +125°C.
