Memory - 7037L20PF Application Field and Working Principle

7037L20PF (7037L20PF) is a 2W8 (two-way eight-port) rotary switch developed by Yamaha Corporation and made up of four integrated logic circuits. It is mainly used to route signals between multiple components, like amplifiers, instruments, and other related audio devices. It is suitable in applications that require high signal accuracy, isolation across different signals, and reliable transistor noise reduction.

Application Field

7037L20PF can be used in various audio and music applications, like headphone amplifiers, cable splitters, sound output controllers, and other audio-related devices. The device is capable of supporting extensive complex audio circuitry operations, such as signal switching and gain compensation. In addition to these, it is also applied in automotive audio and home entertainment systems for routing audio signals.

Working Principle and Features

The working principle behind 7037L20PF lies in its integrated four logic circuits. It uses two SPDT (single-pole, double-throw) transistor switches, which enable the selection of one of two ports and route the respective signals directly to the output. The integrated four logic circuits further provide additional isolation and provide high level accuracy that can maintain signal fidelity over a long period of time.Its built-in four way adjustable logic circuit allows for analog/digital signal switching and gain compensation. Its rocker-style selector allows for inputs and outputs to be selected quickly and easily. The device also features a built-in voltage regulator that can reduce power noise on the audio signals, thus resulting in higher quality audio output.Lastly, the device\'s form factor is designed with optimal space utilization in mind, which makes it highly suitable for use in tight spaces or panels with limited space. It also features a low-profile profile, allowing for easy placement and installation in devices.

Conclusion

The 7037L20PF is a highly versatile 2W8 rotary switch that is suitable for routing signals between multiple components in various audio-related applications. Its integrated four logic circuits provide a high level of accuracy and reliability, while its built-in voltage regulator improves the quality of audio output. Furthermore, its form factor is highly suitable for use in tight spaces or panels with limited space, making it an ideal choice for many audio applications.
