The CA3018 and CA3018A consist of four general purpose
silicon NPN transistors on a common monolithic substrate.
Two of the four transistors are connected in the Darlington
configuration. The substrate is connected to a separate
terminal for maximum flexibility.
The transistors of the CA3018 and the CA3018A are well
suited to a wide variety of applications in low power systems
in the DC through VHF range. They may be used as discrete
transistors in conventional circuits but in addition they
provide the advantages of close electrical and thermal
matching inherent in integrated circuit construction.
The CA3018A is similar to the CA3018 but features tighter
control of current gain, leakage, and offset parameters
making it suitable for more critical applications requiring
premium performance.
