High Voltage Power Operational Amplifiers


Apex introduces PA34x series high voltage monolithic MOSFET OP AMPs


The PA340, PA341, and PA343 from Apex Microtechnology are high voltage monolithic MOSFET operational amplifiers that provide increased reliability while achieving performance features previously found only in hybrid designs.

Inputs are protected from excessive common mode and differential mode voltages. The Safe Operating Area (SOA) has no second breakdown limitations. External compensation provides the user flexibility in choosing optimum gain and bandwidth for the application.
