Its four channels of video input signals can be randomly switched at megahertz rates to the single output. In addition, multiple devices can be configured in either parallel or cascade arrangements to form switch matrices. This flexibility in using the AD9300 is possible because the output of the device is in a high-impedance state when the chip is not enabled; when the chip is enabled, the unit acts as a buffer with a high input impedance and low output impedance. An advanced bipolar process provides fast, wideband switching capabilities while maintaining crosstalk rejection of 72 dB at 10 MHz. Full power bandwidth is a minimum 27 MHz. The device can be operated from ± 10 V to ± 15 V power supplies. The AD9300K is available in a 16-pin ceramic DIP and a 20-pin PLCC and is designed to operate over the commercial temperature range of 0°C to +70°C. The AD9300TQ is a hermetic 16-pin ceramic DIP for military temperature range (–55°C to +125°C) applications. This p...
