3580 series first family ntegrated Circuit operational amplifiers which will provide output voltage swings 145V monolithic F-ET input stage bias currents (20pA) which minimizes offset voltages caused bias current large resistance normally associated with high voltage circuits. 3580 series packaged TO-3 package which will dissipate over power without heat sink 4.5W with suitable heat sink. input stage protected against overvoltages output stage protected against short-circuitsto-ground. special thermal sensing circuit prevents damage amplifier automatically shutting amplifier down when much power being dissipated.

advantages normally available modular discrete component units. amplifiers have thermal sensing shut-off circuitry which automatically turns amplifier when internal temperature reaches approximately 150°C. This accomplished sensing substrate temperature deactivating input stage current source when temperature reaches critical level. this happens, output load current limits safe value amplifier's quiescent current decreases. cause abnormal power dissipation continuous (such short circuit across load) output current remain value oscillate between values d-ependi-ng amount power being dissipated heat sink conditions seen amplifier. either case, amplifier will sustain internal damage will return normal operation within seconds after abnormal condition removed. incorporation thermal sensing shut-off amplifier will allow smaller heat sink than would otherwise required. This fact that amplifier will protect itself does require massive heat sink protection under abnormal conditions. Another unique feature 3580 family thorough testing unit receiver. addition normal tests, amplifiers 100% tested input protection full rated differential voltage Each unit also 100% tested output maximum supply voltage. that these short circuit common

This accomplished true cascode input stage which keeps drain-to-source voltage input transistors constant common-mode voltage changes.

When amplifiers operated from single supply, voltage across output transistors high enough that secondary breakdown consideration. output current must limited order prevent damage. This done keeping load resistor larger than 3582 greater than 3581.
