GENERAL DESCRIPTION  
Differential signal processing reduces the effects of ground noise  
which 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 a low-cost differential or single-ended input to  
differential output amplifier with resistor-settable gain. The  
AD8132 is a major advancement over op amps for driving differ-  
ential 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.  
The AD8132 is available in both SOIC and µSOIC packages for  
operation over –40°C to +85°C temperatures.  
Manufactured on ADI’s next generation of XFCB bipolar pro-  
cess, 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 VOCM  
pin, easily level-shifting the input signals for driving single supply  
ADCs. Fast overload recovery preserves sampling accuracy.

The AD8132 can also be used as a differential driver for the  
transmission 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 can  
be used for either analog or digital video signals or for other high-  
speed data transmission. The AD8132 is capable of driving either  
cat3 or cat5 twisted pair or coaxial with minimal line attenu-  
ation. The AD8132 has considerable cost and performance  
improvements over discrete line driver solutions.
