Overview
The RS2105XN is a dual single-pole double-throw (SPDT) analog switch manufactured by Runic Technology. It operates within a supply voltage range of +1.8V to +5.5V and features a typical on-state resistance of 0.5Ω, with a maximum rating of 1Ω. The device supports a -3dB bandwidth of 30MHz and offers fast switching speeds, typically 50ns for turn-on and 15ns for turn-off. It includes two channels configured as 2:1 multiplexers in a 10-MSOP package. Leakage current is limited to a maximum of 1µA, and channel capacitance is 80pF. The component functions across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low on-resistance design facilitates efficient signal transmission with minimal power loss.
- Rail-to-rail operation allows handling of both analog and digital signals across the full supply range.
- TTL/CMOS compatible control logic ensures seamless integration with standard digital interfaces.
Applications
- Signal gating and chopping circuits
- Modulation or demodulation systems such as modems
- Signal multiplexing for analog-to-digital and digital-to-analog conversion
- Battery-operated equipment and wearable devices
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure that the selected package variant matches the intended PCB layout requirements. Cross-reference the RoHS status and moisture sensitivity level with project specifications before finalizing procurement orders.
Selection Notes
Select this component when low voltage operation below 5.5V is required alongside high-speed switching capabilities. The dual SPDT configuration is suitable for applications needing independent signal routing without external multiplexing logic. Consider the 10-MSOP package dimensions for space-constrained designs requiring surface-mount assembly.
Part Context
The RS2105XN belongs to Runic Technology's portfolio of analog mixed-signal integrated circuits. It is part of the RS2105 series, which focuses on low on-resistance performance for portable electronics. This family targets applications demanding high reliability in battery-powered environments where power efficiency and signal integrity are critical.
Replacement Considerations
Consult official substitution lists for equivalent dual SPDT switches with comparable on-resistance and voltage ratings. Verify pin-to-pin compatibility if replacing in existing designs. Ensure alternative components support the same -40°C to +125°C operating temperature range.
