The CJ3400 is typically packaged in a dual-in-line package (DIP) format. This type of packaging allows for easy integration into printed circuit boards (PCBs) and facilitates through-hole mounting, making it suitable for various electronic applications.

The CJ3400 is a quad operational amplifier (op-amp) housed in a 14-pin dual in-line package (DIP). Each of the four op-amps can be used independently, allowing for various analog signal processing tasks. The primary functions include amplification, summation, and filtering of analog signals.
Pin configuration typically includes the following:
- Pins 1, 2, 3, 4: Non-inverting inputs of the four op-amps (1A, 2A, 3A, 4A).
- Pins 5, 6, 7, 8: Inverting inputs of the four op-amps (1B, 2B, 3B, 4B).
- Pins 9, 10, 11, 12: Outputs of the four op-amps (1Y, 2Y, 3Y, 4Y).
- Pin 13: Offset Null for the first op-amp.
- Pin 14: Power supply connection, typically V+.
The CJ3400 is favored for its versatility and ease of use in various electronic applications.

The CJ3400 is manufactured by the company CJ Electronics, a South Korean company that specializes in electronics and technology products. CJ Electronics is a subsidiary of CJ Group, which is known for its diverse range of businesses, including food production, entertainment, and logistics. The company focuses on innovation in consumer electronics, providing high-quality products such as televisions, home appliances, and various electronic devices.
