GENERAL DESCRIPTION
The AD8131 is a differential or single-ended input to
differential output driver requiring no external components for
a fixed gain of 2. The AD8131 is a major advancement over op
amps for driving signals over long lines or for driving
differential input ADCs. The AD8131 has a unique internal
feedback feature that provides output gain and phase matching
that are balanced to 60 dB at 10 MHz, reducing radiated EMI
and suppressing harmonics. Manufactured on the Analog
Devices, Inc. next generation XFCB bipolar process, the
AD8131 has a 3 dB bandwidth of 400 MHz and delivers a
differential signal with very low harmonic distortion.
The AD8131 is a differential driver for the transmission of
high-speed signals over low-cost twisted pair or coax cables.
The AD8131 can be used for either analog or digital video
signals or for other high-speed data transmission. The AD8131
driver is capable of driving either Cat3 or Cat5 twisted pair or
coax with minimal line attenuation. The AD8131 has
considerable cost and performance improvements over discrete
line driver solutions.
The AD8131 can replace transformers in a variety of applications,
preserving low frequency and dc information. The AD8131 does
not have the susceptibility to magnetic interference and hysteresis
of transformers. It is smaller, easier to work with, and has the high
reliability associated with ICs.

The AD8131’s differential output also helps balance the input
for differential ADCs, optimizing the distortion performance of
the ADCs. The common-mode level of the differential output is
adjustable by a voltage on the VOCM pin, easily level-shifting the
input signals for driving single-supply ADCs with dual supply
signals. Fast overload recovery preserves sampling accuracy.
The AD8131 is available in both SOIC and MSOP packages for
operation over 40°C to +125°C.
