The low ON resistance of the QS4A105 allows inputs to be connected to outputs with low insertion loss and high bandwidth. The QS4A105, with 1.3GHz bandwidth, is ideal for high-performance video signal switching, audio signal switching, and telecomm routing applications. Low power dissipation makes this device ideal for battery operated and remote instrumentation applications. The QS4A105 is offered in the QSOP package which has several advantages over conventional packages such as PDIP and SOIC, including: Reduced signal delays due to denser component packaging on circuit boards Reduced syste...
