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.
GENERAL DESCRIPTION
The AD8129/AD8130 are designed as receivers for the
transmission of high speed signals over twisted-pair cables to
for analog or digital video signals and for high speed data
transmission.

Figure 2. AD8129 CMRR vs. Frequency
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.
