APPLICATIONS
Low power differential ADC drivers
Differential gain and differential filtering
Video line drivers
Differential in/out level shifting
Single-ended input to differential output drivers
Active transformers
The AD8132 is also used as a differential driver for the trans-
mission of high speed signals over low cost twisted pair or coaxial
cables. The feedback network can be adjusted to boost the high
frequency components of the signal. The AD8132 is used for either
analog or digital video signals or for other high speed data trans-
mission. The AD8132 is capable of driving either a Category 3
or Category 5 twisted pair or coaxial cable with minimal line
attenuation. The AD8132 has considerable cost and performance
improvements over discrete line driver solutions.
Differential signal processing reduces the effects of ground noise
that plagues ground-referenced systems. The AD8132 can be
used for differential signal processing (gain and filtering) through-
out a signal chain, easily simplifying the conversion between
differential and single-ended components.
The AD8132 is available in both SOIC_N and MSOP packages
for operation over the extended industrial temperature range of
−40°C to +125°C.

GENERAL DESCRIPTION
The AD8132 is a low cost differential or single-ended input to
differential output amplifier with resistor set gain. The AD8132
is a major advancement over op amps for driving differential input
ADCs or for driving signals over long lines. The AD8132 has a
unique internal feedback feature that provides output gain and
phase matching balanced to −68 dB at 10 MHz, suppressing
harmonics and reducing radiated EMI.
Manufactured using the next generation of Analog Devices, Inc.’s
XFCB bipolar process, the AD8132 has a −3 dB bandwidth of
350 MHz and delivers a differential signal with −99 dBc SFDR
at 5 MHz, despite its low cost. The AD8132 eliminates the need for
a transformer with high performance ADCs, preserving the low
frequency and dc information. The common-mode level
of the differential output is adjustable by applying a voltage on
the V
OCM
pin, easily level shifting the input signals for driving
single-supply ADCs. Fast overload recovery preserves sampling
accuracy.
