The AD8113 is a fully buffered crosspoint switch matrix that
operates on
±
12 V for audio applications and
±
5 V for video
applications. It offers a –3 dB signal bandwidth greater than
60 MHz and channel switch times of less than 60 ns with 0.1%
settling for use in both analog and digital audio. The AD8113
operated at 20 kHz has crosstalk performance of –83 dB and
isolation of 90 dB. In addition, ground/power pins surround all
inputs and outputs to provide extra shielding for operation in
the most demanding audio routing applications. The differential
gain and differential phase of better than 0.1% and 0.1°, respec-
tively, along with 0.1 dB flatness out to 10 MHz, make the
AD8113 suitable for many video applications.
The AD8113 includes 16 independent output buffers that can
be placed into a disabled state for paralleling crosspoint outputs
so that off channel loading is minimized. The AD8113 has a
gain of +2. It operates on voltage supplies of
±
5 V or
±
12 V
while consuming only 34 mA or 31 mA of current, respectively.
The channel switching is performed via a serial digital control
(which can accommodate daisy-chaining of several devices) or
via a parallel control, allowing updating of an individual output
without reprogramming the entire array.
The AD8113 is packaged in a 100-lead LQFP and is available
over the commercial temperature range of 0°C to 70°C.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent 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.
2
Specification is for device in free air (T = 25°C):
A
100-lead plastic LQFP (ST):
θ
JA
= 40°C/W.
3
To avoid differential input breakdown, in no case should one-half the output
voltage (1/2 V
OUT
) and any input voltage be greater than 10 V potential differen-
tial. See output voltage swing specification for linear output range.
The AD8113 is operated with
±
5 V to
±
12 V supplies and
can drive loads down to 150
Ω
(± 5 V) or 600
Ω
(± 12 V),
resulting in a large range of possible power dissipations. For
this reason, extra care must be taken derating the operating
conditions based on ambient temperature.
Packaged in a 100-lead LQFP, the AD8113 junction-to-ambient
thermal impedance (θ
JA
) is 40°C/W. For long-term reliability,
the maximum allowed junction temperature of the plastic-
encapsulated die should not exceed 150°C. Temporarily exceeding
this limit may cause a shift in parametric performance due to a
change in the stresses exerted on the die by the package. Exceeding
a junction temperature of 175°C for an extended period can result
in device failure. The following curve shows the range of allowed
power dissipations that meet these conditions over the commercial
range of ambient temperatures.

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 the AD8113 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.
