GENERAL DESCRIPTION

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 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 is packaged in a 100-lead LQFP and is available

over the commercial temperature range of 0°C to 70°C.
