... Low Power, High Voltage SPST Analog Switches DESCRIPTION The DG447 and DG448 are dual supply single-pole/single- throw (SPST) switches. On resistance is 25 Ω maximum and flatness is 2.2 Ω 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 ...
