CA 3086

The CA 3086 is a versatile analog integrated circuit comprising five matched NPN transistors in a single array. Engineered for precision low-noise amplification and reliable switching, this compact component is suitable for a variety of analog tasks where consistent transistor performance is required. Matching tolerance within 2% to ensure uniform gain and predictable behavior across all five transistors. 20V voltage rating for stable operation in low to moderate voltage circuits. 15mA collector current capacity that supports a broad range of signal processing and biasing requirements. Low noise figure to preserve signal fidelity in sensitive analog and audio stages. Compact 14-pin dual in-line package for efficient integration into standard circuit boards. Compared with earlier transistor arrays, the CA 3086 delivers improved matching accuracy and reduced noise, benefits that directly enhance linearity and gain consistency among transistor elements. These characteristics are particularly valuable in audio preamplifiers, instrumentation amplifiers, differential stages, and active filters where predictable transistor pairs reduce the need for external balancing and trimming. By integrating multiple matched transistors into a single package, the CA 3086 simplifies circuit design, reduces board space, and improves overall reliability by minimizing the number of discrete components. Its combination of tight matching, modest voltage and current ratings, and low-noise performance makes it a practical choice for engineers seeking compact, predictable analog building blocks in precision and audio applications.
