Overview
The FSA2466UMX is a dual double-pole double-throw (DPDT) analog switch IC manufactured by onsemi, designed for low-voltage data and audio signal routing. It operates within a supply voltage range of 1.65 V to 4.45 V and features a maximum on-resistance of 2 Ohms. The device supports a DC switch current of 350 mA with a maximum power consumption of 100 nA. Signal integrity is maintained through fast switching speeds, characterized by a maximum turn-on time of 50 ns and a maximum turn-off time of 32 ns. It functions reliably across an extended temperature range from -40°C to +85°C and is housed in a UQFN-16 surface-mount package.
Feature Summary
- Dual DPDT configuration enables simultaneous switching of two independent signal paths for efficient data or audio line management.
- Low on-resistance of 2 Ohms ensures minimal signal attenuation and high fidelity for sensitive audio and data applications.
- Ultra-low power consumption of 100 nA maximizes battery life in portable electronic devices.
- Fast switching times of 50 ns (on) and 32 ns (off) support high-speed digital and analog signal routing requirements.
Applications
- Portable consumer electronics requiring low-power signal switching
- Audio equipment for input selection and mute functions
- Data bus multiplexing in mobile communication devices
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard SMD/SMT assembly processes. Confirm RoHS compliance status via the latest datasheet before integration into regulated products.
Selection Notes
Select this component when a dual-channel DPDT topology is required for low-voltage analog or digital signals. The 2 Ohm on-resistance suits applications demanding low insertion loss. Verify that the operating voltage remains within the 1.65 V to 4.45 V range and that the 350 mA DC current limit meets load requirements.
Part Context
This part belongs to the FSA2466 series of analog switches from onsemi. It is categorized under Analog Switch ICs and falls within the broader Switch ICs subcategory. The device is distinct from crosspoint switches like the FSA2866, focusing specifically on dual DPDT functionality rather than matrix routing.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives within the same series. Verify electrical parameters such as on-resistance and supply voltage ranges match the original design requirements before replacing.
