GENERAL DESCRIPTION
The AD8112 is a low cost, 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
AD8112 operated at 20 kHz has a 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.
With a differential gain and differential phase better than 0.1%
and 0.1°, respectively, and a 0.1 dB flatness output of up to 10 MHz,
the AD8112 is suitable for many video applications.
The AD8112 includes eight independent output buffers that can
be placed into a disabled state for paralleling crosspoint outputs
so that off channel loading is minimized. The AD8112 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 the daisy chaining of several devices) or via
a parallel control, allowing updating of an individual output
without reprogramming the entire array.
The AD8112 is packaged in a 100-lead LQFP and is available
over the commercial temperature range of 0°C to 70°C.
