The FSA2268UMX is a low-power, bidirectional analog switch device from Texas Instruments capable of switching voltages up to about 2.5 V. This analog switch has one digital control pin that operates in either single-pole/single-throw (SPST) or single-pole/double-throw (SPDT) configuration. The analog switch is suitable for use in a variety of applications, including communications, instrumentation, programmable and automatic test systems, data acquisition, and power management. This article will discuss the application field, working principle and key features of the FSA2268UMX.

Application Field

The FSA2268UMX is an ideal choice for applications where low on-resistance and power consumption are key factors, such as communications line switching, power management, and audio/video data routing. This device is suitable for use in applications where bidirectional switching of analog signals is necessary, such as in data acquisition systems, programmable test systems, and remote sensing. This device is also commonly used to help reduce power consumption by switching off unused portions of the system.

Working Principle

The FSA2268UMX is a bidirectional analog switch with a digital control pin. This digital pin can be controlled by a logic signal in either a single-pole/single-throw (SPST) or single-pole/double-throw (SPDT) configuration. When the control pin is set to its low voltage state, the switch is open and no current can flow through the switch. When the control pin is set to its high voltage state, the switch is closed, allowing current to flow through the switch. The analog switch has a maximum voltage rating of 2.5 V, a typical on-resistance of 15 ohms, and a maximum supply current of 50 µA.

Key Features

The FSA2268UMX analog switch is designed to provide low-power switching of analog signals. The device is available in an 8-pin TSSOP package and is RoHS-compliant. Its key features include low supply current, low on-resistance, bidirectional switching, and single-pole/single-throw (SPST) or single-pole/double-throw (SPDT) control configurations. It has a maximum supply voltage of 2.5 V and a maximum on-resistance of 15 ohms, making it ideal for low power applications. It is also able to switch signals from DC to 1.5 MHz, making it suitable for a variety of applications.
