AD8137:  Low Cost, Low Power Differential ADC Driver

Product Description

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 feedback networks consisting of four resistors determine the amplifier's closed-loop gain. The power-down feature is beneficial in critical low power applications.

The AD8137 is available in the small 8-lead SOIC package and 3x3mm LFCSP. It is rated to operate over the extended industrial temperature range of -40°C to +125°C.
