DG449 Vishay Siliconix High Voltage Single SPDT Analog Switch in SOT23-8 DESCRIPTION The DG449 is a dual supply single-pole/double-throw (SPDT) switches. On resistance is 38  and flatness is 2.6  max over the specified analog signal range. These analog switches were designed to provide high speed, low error switching of precision analog signals. The primary application areas are in the routing and switching in telecommunications and test equipment. Combining low power, low leakages, low on-resistance and small physical size, the DG449 is also ideally suited for portable and battery powered industrial and military equipment. The DG449 operates either from a single + 7 V to 36 V supply or from dual ± 4.5 V to ± 20 V supplies. It is offered in the very popular, small SOT23-8 package.
