CA3046 General Purpose NPN Transistor Array (DIP-14)

The CA3046 is a highly versatile monolithic integrated circuit that features five general-purpose NPN transistors. These transistors are fabricated on a common substrate, providing exceptional thermal tracking and electrical matching characteristics that are difficult to achieve with discrete components. Two of the transistors are specifically connected as a differential pair, making this IC an ideal choice for differential amplifiers, temperature-compensated amplifiers, and mixer circuits. The remaining three transistors can be used independently for various functions such as signal switching, regulation, or as part of a current mirror. Because all five transistors reside on the same silicon die, the CA3046 ensures consistent performance across temperature variations, making it a staple in precision analog design and educational electronics.

Key Features:

Two transistors are internally connected to form a differentially connected pair.

Excellent parameter matching for high stability in balanced circuit designs.

Operates with low noise and high gain over a wide frequency range.

Versatile applications ranging from DC to 120MHz frequency response.

Compact 14-pin DIP package for easy integration and breadboard prototyping.
