Description

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.
