Apex Microtechnology PA142A
The PA141/PA142 are high voltage monolithic MOSFET operational amplifiers achieving performance features previously found only in hybrid designs while increasing reliability. The safe operating area (SOA) has no second breakdown limitations and can be observed with all type loads by choosing an appropriate current limiting resistor. The PA141 is packaged in a hermetically sealed TO-3 and all circuitry is isolated from the case by an aluminum nitride (AlN) substrate.| Part No. | PA142A |
