Systems Operating Anywhere in the
Frequency Range from DC to VHF
Custom Designed Differential Amplifiers
Temperature Compensated Amplifiers 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
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 SOIC package. Schematic and Connection Diagram Figure 1. SOIC Package

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
