General Description
The LM3046 consists of five general purpose silicon NPN
transistors on a common monolithic substrate. Two of the
transistors are internally connected to form a
differentially-connected pair. The transistors are well suited
to a wide variety of applications in low power system in the
DC through VHF range. They may be used as discrete tran-
sistors in conventional circuits however, in addition, they pro-
vide the very significant inherent integrated circuit advan-
tages of close electrical and thermal matching. The LM3046
is supplied in a 14-lead molded dual-in-line package.
