LOW VOLTAGE DUAL-SPDT (0.4OHM) A
Stock Quantity: 0
The FSA2269TSUMX, manufactured by Fairchild Semiconductor (FSC), is a low-voltage, dual Single-Pole Double-Throw (SPDT) analog switch characterized by a typical on-resistance (RON) of 0.4 ohms. This device is designed for switching analog or digital signals in applications with stringent low-distortion requirements. The dual SPDT configuration allows for multiplexing or demultiplexing of two independent signals. Key specifications include a low operating voltage range, typically 1.65V to 5.5V, making it suitable for portable and battery-powered applications. The FSA2269TSUMX features break-before-make switching action to prevent momentary shorting of signals during switching transitions. Its low on-resistance minimizes signal attenuation and distortion, while the low total harmonic distortion (THD) performance ensures signal integrity. The device is commonly used in audio and video signal routing, as well as data switching applications where minimal signal degradation is critical.
