The CPC7512 dual 1-Form-A high-voltage, high-frequency, shunt-isolated analog switch builds upon IXYS Integrated Circuits Division's design and fabrication expertise for industrial applications. This monolithic solid state device provides the switching functionality of two normally open (1-Form-A) solid state relays for high frequency applications in one small economical package. Both switches incorporate shunt isolation by means of a T-switch compensation technique to minimize series capacitance through the open off-state switches for improved off-state isolation over frequency. Designed to provide flexible single-ended or differential access to high voltage networks, the CPC7512 is functionally configured as two independent logical switches. The self-biasing switches do not require external high-voltage supplies for proper operation. An integrated thermal shutdown feature provides not only enhanced protection for devices connected to high voltage networks up to +320V, but also an external signal to indicate the device is shut down.
