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.Applications CCTV surveillance/DVR Analog/digital audio routers Video routers (NTSC, PAL, S-Video, SECAM) Multimedia systems Video conferencing
