Vishay Siliconix Analog Switches and Multiplexers provide benchmark performance in a broad array of end products. Products include multi-channel data acquisition systems, process control and automation, instrumentation, video systems, healthcare and portable consumer electronics. The devices are offered in a number of package options to meet specific application requirements, including the TSSOP, SOIC, miniQFN, MICRO FOOT®, and more. They support both single and dual supply operation. On-resistance values range from sub 1Ω to 10Ω and above. Switch configurations include SPST, SPDT, DPST, DPDT, and bus switches while multiplexers include 2:1, 4:1, 8:1, and 16:1 and differential configurations.
Vishay has made several recent additions to its lines with products that extend operation voltage range down to 1.6V, bring ±15V switches ON resistance to 1.5Ω, lower the charge injection to sub-picocoulomb range and offer signal bandwidth up to 1GHz. The devices have been designed to meet the requirements of a variety of applications and can be categorized as follows: - Low Charge Injection Devices are optimized for precision switching applications with minimal charge injection during both ON and OFF transitions. The low switching glitches and fast settling times make these devices ideal in sample and hold applications, data acquisition, and precision ADC input multiplexing. - Low On-Resistance Devices have a low on-resistance (typically 0.3Ω to 8Ω). A wide range of operating voltages is available for various applications like audio and video switching, programmable gain control, power routing and mechanical relay replacement. - High-Bandwidth devices are optimized for high-bandwidth applications like high-speed mixed-signal switching and filtering. The devices support frequencies up to 1GHz. Devices optimized for this application require moderately low on-resistance to reduce signal insertion losses, low parasitic capacitance, high cross talk rejection and high off isolation. - Low-Voltage Devices for Consumer Handheld and Portable Instrumentation are optimized for low and flat resistances down to a supply voltage of 1.6V. This family of devices includes specialized devices for high-bandwidth USB applications, audio applications requiring negative voltage swings and fault protected switches designed to offer over current, break before make, make before break, or power down protection.
