Overview
The NLAS3899BMNTXG is a dual low on-resistance analog switch IC manufactured by onsemi. It features four channels configured as two double-pole double-throw (DPDT) switches within a QFN-16 package. The device operates on a single supply voltage ranging from 1.65 V to 4.3 V, with a maximum power consumption of 2 µA. Key electrical parameters include a maximum on-resistance of 2.5 Ohms, a maximum turn-on time of 40 ns, and a maximum turn-off time of 30 ns. It supports a DC switch current of 300 mA and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual DPDT configuration providing four independent signal paths in a compact footprint
- Low on-resistance characteristic ensuring minimal signal attenuation for high-fidelity switching
- Ultra-low quiescent current design optimized for battery-powered portable applications
Applications
- Portable consumer electronics requiring efficient signal routing
- Audio and video signal path switching in mobile devices
- Battery-operated instrumentation with strict power constraints
Procurement Notes
Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific manufacturing lot. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Validate that the QFN-16 package dimensions align with the target PCB layout specifications.
Selection Notes
Select this component when dual DPDT switching functionality is required within tight space constraints. Consider the 1.65 V minimum operating voltage for compatibility with low-power logic interfaces. Evaluate the 2.5 Ohm on-resistance against signal integrity requirements for the intended application bandwidth. Verify thermal performance within the specified -40°C to +85°C operational range.
Part Context
This part belongs to the NLAS3899 series of analog switches designed for portable devices. It represents onsemi's focus on low-power signal management solutions. The QFN-16 package provides a small form factor suitable for dense PCB layouts. The series emphasizes low on-resistance and fast switching speeds for modern mobile applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Check manufacturer announcements for direct replacements or pin-compatible alternatives within the same product family.
