Overview
The MP2736DQG-LF-P is a dual single-pole double-throw (SPDT) analog switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 3.3 V and features a maximum on-resistance of 450 mΩ. The device provides two independent channels in a QFN-10 package, suitable for surface-mount installation. Signal switching performance includes a maximum turn-on time of 36 ns and a maximum turn-off time of 30 ns. The component supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.
Feature Summary
- Dual SPDT configuration providing two independent signal paths
- Low on-resistance for minimal signal attenuation
- Fast switching speeds for high-frequency applications
- Compact QFN-10 footprint for space-constrained designs
Applications
- Portable electronic devices requiring signal routing
- Audio and video signal switching circuits
- Communication equipment interface protection
- Test and measurement instrument signal paths
Procurement Notes
Verify the specific ordering suffix to confirm packaging details, as the P suffix indicates reel packaging. Ensure compatibility with standard surface-mount assembly processes. Confirm that the 3.3 V maximum supply voltage aligns with the target system power rails. Check for lead-free compliance documentation if required by regulatory standards.
Selection Notes
Select this component when dual isolated signal paths are required within a low-voltage environment. The 450 mΩ on-resistance is suitable for general-purpose analog signals but may require verification for high-current applications. Consider the QFN-10 thermal characteristics if multiple switches operate simultaneously. Compare against single-channel alternatives if only one path is needed to optimize board space.
Part Context
This part belongs to the MP2736 series of low-voltage analog switches. It shares core specifications with variants such as the MP2736DQG-LF-Z, differing primarily in packaging quantity or tape-and-reel specifications. The series is designed for portable electronics where low power consumption and small form factors are critical.
Replacement Considerations
The MP2736DQG-LF-Z serves as a direct functional substitute with identical electrical characteristics. Verify pinout compatibility before substitution. Other dual SPDT switches from different manufacturers may require circuit redesign due to differences in on-resistance or control logic.
