3580

      The 3580 series is a kind of high voltage operational amplifiers. It the first family of integrated circuit operational amplifiers which will provide output voltage swings of up to ±145V.The monolithic F--ET input stage has low bias currents(20pA) which minimizes the offset voltages caused by the bias current and the large resistance normally associated with high voltage circuits. The 3580 series is packaged in a TO-3 package which will dissipate over 3W of power without a heat sink and 4.5W with a suitable heat sink.The input stage is protected against overvoltages and the output stage is protected against short-circuitsto-ground. 

      It has three features .The first one is the large load currents which is up to -60mA and +60mA.The second one is that it is difficult to damage because of its automantic thermal shutoff . The third one is reduces source loading which is 1011Input Z .The third one is preserues system accuracy which is 11OdB CMR 2OpA bias current.
