The CA3096 consists of an NPN differential amplifier pair and three general-purpose NPN transistors. The inclusion of a pre-matched differential pair makes it particularly well-suited for applications requiring sensitive amplification of differential signals, while the remaining transistors can be used for additional gain stages, current sources, or other circuit functions.

Applications

• Instrumentation Amplifiers: High-precision amplification of sensor signals.
• Low-Noise Amplifiers: Amplification of weak signals with minimal added noise.
• Operational Amplifiers: As a building block for custom op-amp designs.
• Voltage Comparators: Comparing two voltages and producing a digital output.
• Balanced Modulators/Demodulators: Signal processing in communication systems.

Features

• Matched NPN Differential Pair: Provides excellent common-mode rejection and thermal stability.
• Three Additional NPN Transistors: Offers flexibility in circuit design.
• Monolithic Construction: Ensures close matching of transistor characteristics.
• High Gain: Provides high amplification for weak signals.
• Wide Operating Voltage Range: Can operate over a range of supply voltages.

Benefits

• Improved Circuit Performance: Matched differential pair enhances accuracy and stability.
• Reduced Component Count: Integrates multiple transistors into a single package.
• Simplified Circuit Design: Easier to implement complex analog functions.
• Cost Savings: Reduced component count and assembly costs.
• Space Savings: Compact package minimizes board space requirements.

The CA3096M96 is packaged in an SO-16 (Small Outline) package. Typical specifications would include a collector-emitter breakdown voltage (BVCEO) of around 40V, a collector current (IC) of up to 50mA, and a transition frequency (fT) around 100 MHz for the individual transistors. The key advantage is the closely matched characteristics of the differential pair. As the part is end-of-life, modern alternatives might be considered for new designs.
