GENERAL DESCRIPTON  
The AD8137 is a low cost differential driver with a rail-to-rail  
output that is ideal for driving ADCs in systems that are sensitive  
to power and cost. The AD8137 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 inherently balanced  
outputs as well as suppression of even-order harmonic distortion  
products. Fully differential and single-ended-to-differential gain  
configurations are easily realized by the AD8137. External  
closed-loop gain of the amplifier. The power-down feature is  
beneficial in critical low power applications.  
The AD8137 is manufactured on Analog Devices, Inc.,  
proprietary second-generation XFCB process, enabling it to  
achieve high levels of performance with very low power  
consumption.  
The AD8137 is available in the small 8-lead SOIC package and  
3 mm × 3 mm LFCSP package. It is rated to operate over the  
extended industrial temperature range of −40°C to +125°C.  
feedback networks consisting of four resistors determine the
