FSA2866UMX

Analog switches are a type of interface circuitry that allow multiple signals to be selectively connected, sometimes referred to as multiplexers. They can be used to multiplex both analog and digital signals. Applications for analog switches vary greatly and one of the most specialized and compact of them is the FSA2866UMX from Faith Global. This IC is suitable for use in applications requiring multiplexing of both analog and digital signals, including class-D audio amplifiers, DC/DC converter controls, image sensor controllers, precision analog measurement systems, and more.

The FSA2866UMX is built on a patented architecture designed for ultra-low distortion and ultra-low power dissipation. It is a low-voltage analog multiplexer with a fast rise time that can switch up to aI24V signals with a single 3V or 5V supply. It features 2X5 channel selectors and can switch up to 8 independent or 4 fully differential channels. It also features a unique low voltage suppression (LVP) circuit that prevents OUTPUT to GND shorts.

The FSA2866UMX operates by using a fixed voltage (VCTL) to address a particular channel. When the voltage is lower than the voltage of a selected channel, it causes the channel to connect to the OUTPUT port. The LVP circuit also ensures that if VCTL is below a certain voltage, the selected channel is forced to a low state, preventing shorts to other channels. A current controlled source is also used to set the LVP threshold, which can be set for either higher or lower than the VCTL voltage.

The FSA2866UMX is designed for low-distortion and low power consumption and is a good choice for applications requiring very low power dissipation. It is also very compact, making it ideal for applications with limited space. Furthermore, it is highly flexible, allowing for a wide range of uses. With its excellent performance and reliability, it is expected to be a popular choice for many applications in the near future.
