LM3046 LM3046 Transistor Array Literature Number: SNLS372A LM3046 Transistor Array General Description Features 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 differentiallyconnected 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 transistors in conventional circuits however, in addition, they provide the very significant inherent integrated circuit advantages of close electrical and thermal matching. The LM3046 is supplied in a 14-lead molded small outline package. n Two matched pairs of transistors VBE matched 5 mV Input offset current 2 A max at IC = 1 mA n Five general purpose monolithic transistors n Operation from DC to 120 MHz n Wide operating current range n Low noise figure: 3.2 dB typ at 1 kHz Applications n General use in all types of signal processing systems operating anywhere in the frequency range from DC to VHF n Custom designed differential amplifiers n Temperature compensated amplifiers Schematic and Connection Diagram Small Outline Package 00795001 Top View Order Number LM3046M See NS Package Number M14A (c) 2004 National Semiconductor Corporation DS007950 www.national.com LM3046 Transistor Array July 1999 LM3046 Distributors for availability and specifications.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. Note 2: The collector of each transistor is isolated from the substrate by an integral diode. The substrate (terminal 13) must be connected to the most negative point in the external circuit to maintain isolation between transistors and to provide for normal transistor action.
