PRODUCT DE SCRIPT ION
T he AD8079 is a dual, low power, high speed buffer designed
to operate on
±
5 V supplies. T he AD8079’s pinout offers excel-
lent input and output isolation compared to the traditional dual
amplifier pin configuration. With two ac ground pins separating
both the inputs and outputs, the AD8079 achieves very low
crosstalk of less than –70 dB at 5 MHz.
Additionally, the AD8079 contains gain setting resistors factory
set at G = +2.0 (A grade) or Gain = +2.2 (B grade) allowing
circuit configurations with minimal external components. T he
B grade gain of +2.2 compensates for gain loss through a system
by providing a single-point trim. Using active laser trimming of
these resistors, the AD8079 guarantees tight control of gain and
channel-channel gain matching. With its performance and con-
figuration, the AD8079 is well suited for driving differential

cables and transformers. Its low distortion and fast settling are
ideal for buffering high speed dual or differential A-to-D con-
verters.
T he AD8079 features a unique transimpedance linearization
circuitry. T his allows it to drive video loads with excellent differ-
ential gain and phase performance of 0.01% and 0.02
°
on only
50 mW of power per amplifier. It features gain flatness of 0.1 dB
to 50 MHz. T his makes the AD8079 ideal for professional video
electronics such as cameras and video switchers.
T he AD8079 offers low power of 5 mA/amplifier (V
S
=
±
5 V)
and can run on a single +12 V power supply while delivering
over 70 mA of load current. All of this is offered in a small 8-pin
SOIC package. T hese features make this amplifier ideal for por-
table and battery powered applications where size and power are
critical.
T he outstanding bandwidth of 260 MHz along with 800 V/
μ
s of
slew rate make the AD8079 useful in many general purpose high
speed applications where dual power supplies of
±
3 V to
±
6 V
are required.
T he AD8079 is available in the industrial temperature range of
–40
