info

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 economic 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.


  • TTL-logic level inputs activate the high voltage switches.
  • High signal frequency switching and isolation.
  • Provides on-chip galvanic isolation
