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
in

tended 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
work with the AD8131 or AD8132 drivers. Either can be used
f

or analog or digital video signals and for high speed data

transmission.

FREQUENCY (Hz)

02464-002

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 common­mode 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.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

THERMAL RESISTANCE

θJA is specified for the worst-case conditions, that is, θJA is
specified for the device soldered in a circuit board in still air.

Maximum Power Dissipation

The maximum safe power dissipation in the AD8129/AD8130
packages is limited by the associated rise in junction temp­erature (T
glass transition temperature, the plastic changes its properties.
Even temporarily exceeding this temperature limit can change
the stresses that the package exerts on the die, permanently
shifting the parametric performance of the AD8129/AD8130.
Exceeding a junction temperature of 150°C for an extended
period can result in changes in the silicon devices, potentially
causing failure.

depends upon the particular application. The power due to
load drive is calculated by multiplying the load current by the
associated voltage drop across the device. RMS voltages and
currents must be used in these calculations.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
