Overview
The NLAS3799BMUR2G is a dual DPDT analog switch manufactured by onsemi. It features two independent channels housed in a 16-pin VQCCN package with dimensions of 2.6 mm length. The device provides a maximum on-resistance (Ron) of 0.5 Ω and an on-resistance matching specification of 0.05 Ω. It offers a nominal off-isolation of 69 dB. The component operates within standard industrial temperature ranges and complies with lead-free manufacturing standards.
Feature Summary
- Dual independent DPDT switching configuration for signal routing
- Low on-resistance for minimal signal loss
- High off-isolation to prevent channel interference
- Compact surface-mount packaging
Applications
- Portable electronic devices requiring signal path switching
- Audio equipment for input selection
- Test and measurement instrumentation
Procurement Notes
Verify the specific suffix UR2G against official onsemi documentation to confirm tape and reel specifications. Ensure the ordering part number matches the required package variant and moisture sensitivity level. Cross-reference the manufacturer code to distinguish between genuine components and potential counterfeits before procurement.
Selection Notes
Select this component when dual DPDT functionality is required in a compact form factor. Compare the 0.5 Ω Ron against application voltage drops. Verify that the 16-pin VQCCN footprint fits the PCB layout constraints. Confirm compatibility with the system's control logic levels and operating voltage range.
Part Context
This part belongs to the NLAS3799 series of low-power analog switches. It shares functional similarities with other onsemi SPDT and DPDT switches but is distinguished by its dual-channel architecture and specific package dimensions. It serves as a solution for multi-path signal management in space-constrained designs.
Replacement Considerations
Check for direct pin-compatible substitutes within the onsemi portfolio. Verify that alternative parts maintain the same 16-pin VQCCN outline and electrical characteristics such as Ron and isolation.
