FSA2000UMX

Analog Switches - Special Purpose Overview

The FSA2000UMX is a dual SPDT analog switch IC manufactured by Fairchild Semiconductor, now part of onsemi. It operates within a supply voltage range of 1.65 V to 4.4 V and features a maximum on-resistance of 500 mOhms. The device supports a switching DC current of 350 mA with a maximum power supply current of 100 nA. It includes two channels in a UMLP-10 package, with a maximum operating temperature of +85 °C and a minimum of -40 °C. Switching times are specified at a maximum of 55 ns for turn-on and 30 ns for turn-off.

Analog Switches - Special Purpose Feature Summary

• Dual single-pole double-throw (SPDT) configuration for signal routing
• Low on-resistance for minimal signal attenuation
• Ultra-low standby current for battery-powered applications
• Compact UMLP-10 surface-mount packaging

Analog Switches - Special Purpose Applications

• Portable consumer electronics
• Audio signal switching
• Video signal routing
• Battery-operated devices

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer designation as onsemi or Fairchild Semiconductor depending on the production date. Confirm the UMLP-10 package type and RoHS compliance status. Ensure the specific suffix matches the required tape and reel quantity if applicable. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Analog Switches - Special Purpose Selection Notes

Select this component when low on-resistance and high bandwidth are critical for signal integrity. The wide supply voltage range accommodates various logic levels. Consider the thermal performance and package size constraints for dense PCB layouts. Verify that the switching speed requirements align with the specified 55 ns maximum turn-on time.

Analog Switches - Special Purpose Part Context

This device belongs to the FSA2259 series family of analog switches. It shares similar electrical characteristics and packaging with other members of the series, such as the FSA2259. The component is designed for high-performance signal switching in portable applications where space and power consumption are limited.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include the FSA2259UMX and FSA2259UMX_F106 from the same manufacturer. These parts share identical pinouts and electrical specifications. Verify compatibility with existing board designs before substitution.
