The PS392CPE (Current-Programmable Electronically Switched Device) is a versatile continuous-mode analogue switch that is capable of multiple switching functions in a single integrated circuit. It can be used for a wide range of applications, including audio, video, and data recordings. In this article, we\'ll discuss the various application fields and working principles of PS392CPE.

Overview of PS392CPE

The PS392CPE is an advanced, single-chip analog switch with superior electrical performance and stable switching characteristics. It contains two separate, independent switch sections, both controlled by a single current-programmable input. It is designed to operate over a wide range of supply voltages and temperatures and features a fast turn-off time, low power consumption, low thermal resistance, and high EMI immunity. The PS392CPE is available in a variety of package options and can be configured for either simultaneous or individual switching.

Application Fields of PS392CPE

The PS392CPE is suitable for a wide range of applications, including audio and video signal routing, data recording and playback, peak predictive recording, and switching of telecommunication applications. It is also commonly used in power management and automation, digital signal routing, instrumentation and measurement and industrial control.

In audio and video signal routing, the PS392CPE allows signals to be switched in either simultaneous multiplication or individual switching mode. Its fast turn-off time ensures signal integrity while its low thermal resistance permits high-speed signal switching with minimal signal noise.

In power management applications, the PS392CPE is used to switch power when certain voltage or current thresholds are reached. This allows for efficient yet safe operation, as the amount of power drawn is monitored and controlled. In industrial control applications the PS392CPE allows for high-speed, low power switching of signals, enabling electro-mechanical control with minimal interference.

Working Principle of PS392CPE

The PS392CPE utilizes two separate, independent switch sections, each controlled by a single current-programmable input. When a current is applied, it activates the appropriate switch section, allowing for simultaneous or individual switching. The PS392CPE includes two separate, fixed current sources and a single adjustable current source. When current is applied to the adjustable current source, it increases or decreases the current to the appropriate switch section. This action allows for accurate and precise control of the switch sections.

The PS392CPE also operates over a wide range of supply voltages, ensuring that the switch sections are always operating within the correct voltage range. Additionally, its low thermal resistance ensures minimal signal noise, while its high EMI immunity prevents interference with other electronic components.

Conclusion

The PS392CPE is an advanced, single-chip analogue switch that is suitable for a wide range of applications. Its low power consumption and fast turn-off time make it ideal for audio and video signal routing, data recording and playback, power management, and industrial control. Its current-programmable input allows for simultaneous or individual switching, while its wide operating voltage range ensures consistent switching of signals.
