GENERAL DESCRIPTION  
The AD8131 is a differential or single-ended input to differen-  
tial 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 ADI’s 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 can replace transformers in a variety of applica-  
tions preserving low frequency and dc information. The AD8131  
does not have the susceptibility to magnetic interference and  
hysteresis of transformers, while being smaller in size, 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 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 will be available in both SOIC and µSOIC packages  
for operation over –40؇C to +85؇C.
