Introduction to PS391EPE

The PS391EPE is a high-performance analog switch that utilizes monolithic CMOS technology to provide multiplexing and demultiplexing capabilities in hybrid, specialized circuits, and operational amplifiers.The PS391EPE is designed to be used primarily in instrumentation and control systems, communications systems, automotive, medical, and other industry segments. Its low input power and low output impedances make it ideal for a wide range of applications, from high-end, high-speed communication systems to low-cost, low-power consumer electronics.

Applications and Performance

The PS391EPE provides a high-performance analog switch in a small package. It provides a low-noise, high-speed switching interface, which can handle a wide variety of signals. It can switch either single-ended or differential signals, including: AC (voltage level signals); DC (current level signals); and pulse-width modulation signals.The PS391EPE can switch up to 5 V at frequencies up to 1 MHz and 3 V at frequencies up to 10 MHz. It can switch DC voltages up to 45 V, AC voltages up to 15 V peak-to-peak, current levels up to 30 mA, and Pulse Width Modulation (PWM) signals up to 1 cm/s. It also has low input power and low output impedances. The PS391EPE has wide common mode range and is immune to latch-up, allowing it to be used in a variety of high-reliability applications. The device has low temperature drift and low input capacitance and is suitable for use in high-precision systems.

Working Principles

The PS391EPE works by using the voltage level (V) and the charge flow (Q) across a pair of complementary MOSFET transistors. The logic level of the control signal determines which of the two transistors (A or B) is opened or closed.When the logic level of the control signal is low, the A transistor is opened and the B transistor is closed, allowing for current to flow from the input to the output and for the signal to be multiplexed. When the logic level of the control signal is high, the A transistor is closed and the B transistor is opened, allowing for current to flow from the input to the ground and for the signal to be demultiplexed.

Conclusion

In conclusion, the PS391EPE is an excellent choice for high-speed, low-input power, low-impedance analog switching applications. Its small size, wide operating range, and high performance make it a great option for designers and engineers looking to add multiplexing and demultiplexing capabilities to their device. The device also has a low temperature drift, low input capacitance, and high immunity to latch-up, which make it suitable for a wide range of applications.
