Hot-selling and scarce AD8112JSTZ Audio/Video, 60 MHz, 16 × 8, Gain of +2 Crosspoint Switch LQFP100 spot stock

 Product Descriptions

The AD8112 is a low cost,fully buffered crosspoint switch matrixthat operates on ±12 V for audio applications and ±5 V forvideo applications . It offers a −3 dB signal bandwidth greaterthan 60 MHz and channel switch times of less than 60 ns with0.1% settling for use in both analog and digital audio . TheAD8112 operated at 20 kHz has a crosstalk performance of−83 dB and isolation of 90 dB . In addition, ground/power pinssurround all inputs and outputs to provide extra shielding foroperation 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 canbe placed into a disabled state for paralleling crosspoint outputsso that off channel loading is minimized.The AD8112 has a gainof +2. It operates on voltage supplies of ±5 V or ±12 V whileconsuming only 34 mA or 31 mA of current, respectively. Thechannel switching is performed via a serial digital control (whichcan accommodate the daisy chaining of several devices) or viaa parallel control, allowing updating of an individual outputwithout reprogramming the entire array.

The AD8112 is packaged in a 100-lead LQFP and is availableover the commercial temperature range of 0°C to 70°C .
