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.
