3581J

The 3581J is one member of the 3581 family,it is designed as one kind of integrated circuit operational amplifiers which will provide output voltage swings of up to +/-145V.The monolithic FET input stage has low bias currents which minimizes the offset voltages caused by the bias current and the large resistance normally associated with high voltage circuits.It 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-circuits-to-ground.A special thermal sensing circuit prevents damage to the amplifier by automatically shutting the amplifier down when too much power is being dissipated.

Features of the 3581J are:(1)high output swings,up to +/-145V;(2)large load currents,up to +/-60mA;(3)difficult to damage,automatic thermal shutoff;(4)reduces source loading;(5)preserves system accuracy 110dB CMR 20pA bias current.If you want to know more information such as the electrical characterist-ics about the 3581J,please download the datasheet in www.seekic.com or www.chinaicmart.com.
