Overview
The NLAS3799MNR2G is a dual-pole double-throw (DPDT) analog switch manufactured by onsemi. It operates from a single supply voltage ranging from 1.65 V to 5.5 V, supporting bidirectional signal transmission. The device features low on-resistance and excellent channel-to-channel matching for high-fidelity signal routing. It is housed in a compact 16-pin QFN package suitable for surface mount applications.
Feature Summary
- Dual-pole double-throw configuration enabling flexible signal path selection
- Low on-resistance with tight matching specifications for minimal signal distortion
- High off-isolation to prevent signal leakage between channels
- Supports bidirectional data flow across the analog switches
Applications
- Portable multimedia devices requiring audio/video signal switching
- Mobile phones and tablets for antenna or sensor multiplexing
- Consumer electronics utilizing low-voltage signal routing
- Industrial control systems needing isolated signal paths
Procurement Notes
Verify the exact part number suffix against official onsemi documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Cross-reference the manufacturer's latest datasheet revision to validate pinout compatibility and thermal characteristics for your specific PCB layout requirements.
Selection Notes
Select this component when a DPDT topology is required within a low-voltage environment. Ensure the operating voltage range aligns with your system's power rails. Consider the QFN package size for space-constrained designs. Verify that the on-resistance and isolation levels meet your signal integrity requirements compared to alternative single-pole switches.
Part Context
This component belongs to onsemi's NLAS series of low-voltage analog switches. The series is designed for portable applications where power efficiency and small form factors are critical. It complements other signal conditioning and power management solutions offered by the manufacturer for complete system integration.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family. Verify functional equivalence regarding on-resistance and breakdown voltage. Ensure any substitute maintains the same package outline and thermal performance characteristics.
