AD8137YRZ

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 commonmode 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
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.
