Figure 1.  
The AD8129/AD8130 are differential-to-single-ended amplifiers  
with extremely high CMRR at high frequency. Therefore, they  
can also be effectively used as high speed instrumentation amps  
or for converting differential signals to single-ended signals.  
The AD8129 is a low noise, high gain (10 or greater) version  
intended for applications over very long cables, where signal  
attenuation is significant. The AD8130 is stable at a gain of 1  
and can be used for applications where lower gains are required.  
Both have user-adjustable gain to help compensate for losses in  
the transmission line. The gain is set by the ratio of two resistor  
values. The AD8129/AD8130 have very high input impedance  
on both inputs, regardless of the gain setting.  
APPLICATIONS  
High speed differential line receivers  
Differential-to-single-ended converters  
High speed instrumentation amps  
Level shifting  
GENERAL DESCRIPTION  
The AD8129/AD8130 have excellent common-mode rejection  
(70 dB @ 10 MHz), allowing the use of low cost, unshielded  
twisted-pair cables without fear of corruption by external noise  
sources or crosstalk. The AD8129/AD8130 have a wide power  
supply range from single +5 V to 12 V, allowing wide common-  
mode and differential-mode voltage ranges while maintaining  
signal integrity. The wide common-mode voltage range enables  
the driver-receiver pair to operate without isolation transformers  
in many systems where the ground potential difference between  
drive and receive locations is many volts. The AD8129/AD8130  
have considerable cost and performance improvements over  
op amps and other multiamplifier receiving solutions.  
The AD8129/AD8130 are designed as receivers for the  
transmission of high speed signals over twisted-pair cables to  
work with the AD8131 or AD8132 drivers. Either can be used  
for analog or digital video signals and for high speed data  
transmission.
