The FSUSB63UMX belongs to a type of special purpose analog switch, designed with a low on-resistance and simple interface. The switch is particularly well-suited for applications where it is necessary to make an electrical connection between two points using minimal power. The FSUSB63UMX is a microchip-controlled analog switch, with a maximum insertion loss of 1.4 dB and a maximum supply voltage of 5.5 V.

Application Fields

The FSUSB63UMX can be used in a range of applications requiring low on-resistance and a simple interface. This switch is particularly suitable for systems where frequent connection and disconnection of electrical pathways would be expected. It can be used in cell phones, digital cameras, and portable audio players for data conversion, audio switching, and frequency conversions. The FSUSB63UMX can also be used in satellite systems where the switch’s low insertion loss is important to reduce signal fading. It can be used in RF systems such as a microphone mixer and the synthesis of RF sequence generators.

Working Principle & Features

The FSUSB63UMX is a PIN diode-based analog switch, meaning that the switch uses a diode as the main switching element. The electrical connection between two points requires a certain amount of current, and when the gate bias voltage of the switch is exceeded, the current will flow. This PIN diode-based switch is designed with an on-resistance below 20 Ohms and has a common-mode rejection ratio (CMRR) of greater than 20 dB. The FSUSB63UMX analog switch is also designed with a large signal-handling capability of 40Vp (peak-to-peak).

The FSUSB63UMX also features a variety of input control mechanisms, including single-pin control, dual-pin control, and toggle-control. Single-pin control allows the user to control the switch using a voltage or logic signal. Dual-pin control allows for the switching operations to be controlled with two independent input signals. Toggle-control allows for the switching operations to be triggered with a single input signal. The FSUSB63UMX switch also features overvoltage protection, which is beneficial for protecting the switch from high voltages.

Conclusion

The FSUSB63UMX is a type of special purpose analog switch, designed with a low on-resistance and simple interface. It can be used in a range of applications requiring low on-resistance and a simple interface, including cell phones, digital cameras, and portable audio players. The FSUSB63UMX has a variety of input control mechanisms, including single-pin control, dual-pin control, and toggle-control. Additionally it is designed with an on-resistance below 20 Ohms, a CMRR of greater than 20 dB, and a large signal-handling capability of 40Vp.
