They offer a –3 dB signal bandwidth greater than 260 MHz, and channel switch times of less than 25 ns with 1% settling. With –78 dB of crosstalk and –97 dB isolation (@ 5 MHz), the AD8110/AD8111 are useful in many high speed applications. The differential gain and differential phase of better than 0.02% and 0.02 ° respectively, along with 0.1 dB flatness out to 60 MHz, make the AD8110/AD8111 ideal for video signal switching. The AD8110 and AD8111 include eight independent output buffers that can be placed into a high impedance state for paral- leling crosspoint outputs so that off channels do not load the output bus. The AD8110 has a gain of +1, while the AD8111 offers a gain of +2. They operate on voltage supplies of ±5 V while consuming only 50 mA of idle current. The channel switching is performed via a serial digital control (which can accommodate “daisy chaining” of several devices) or via a paral- lel control, allowing updating of an individual output without re- programing the entire array. The AD8110/AD8111 is packaged in an 80-lead TQFP package and is available over the extended industrial temperature range of –40 °C to +85°C. *Patent Pending. |
