GENERAL DESCRIPTON

The AD8137 is manufactured on Analog Devices’ proprietary

second generation XFCB process, enabling it to achieve high

levels of performance with very low power consumption.

The AD8137 is a low cost differential driver with a rail-to-rail

output that is ideal for driving 12-bit 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

3 mm × 3 mm LFCSP. It is rated to operate over the extended

industrial temperature range of −40°C to +125°C.
