The CPC7512 dual 1-Form-A high voltage, high frequency, isolated analog switch builds upon our 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 a compensation method to minimize open-state capacitance for improved off-isolation over frequency. Designed to provide flexible single-ended or differential access to high voltage networks, the CPC7512 is configured as two independent switches with optimized state control. 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.
