Overview
The MP2735DQG-LF-Z is a low-voltage dual single-pole double-throw (SPDT) analog switch manufactured by Monolithic Power Systems. It features an on-resistance of 0.45 ohms and operates within a supply voltage range of 1.65 V to 5.5 V. The device supports bidirectional signal transmission with a breakdown voltage up to 5.5 V. Key electrical parameters include a maximum on-resistance of 0.45 Ω, a maximum off-isolation of -50 dB at 1 MHz, and a propagation delay of 36 ns. It functions reliably across an extended temperature range from -40°C to +85°C and is housed in a compact QFN-10 package.
Feature Summary
- Dual SPDT configuration enabling flexible signal routing for two independent channels
- Low on-resistance of 0.45 ohms ensures minimal signal attenuation
- AEC-Q100 qualified for automotive reliability standards
- Bidirectional signal switching capability supporting wide voltage ranges
Applications
- Automotive infotainment systems requiring robust signal switching
- Portable consumer electronics utilizing low-voltage power supplies
- Industrial control systems needing reliable analog signal routing
Procurement Notes
Verify the specific suffix 'LF-Z' against the manufacturer's current datasheet to confirm lead-free compliance and packaging details. Ensure the QFN-10 footprint matches your PCB design constraints. Cross-reference the AEC-Q100 qualification status if deploying in automotive environments. Confirm availability through authorized distributors as standard stock levels may vary.
Selection Notes
Select this component when a dual-channel SPDT switch is required with low insertion loss. The 0.45 ohm on-resistance is suitable for high-fidelity audio or precision data lines. Consider the QFN-10 package size for space-constrained designs. Verify that the 1.65 V minimum operating voltage aligns with your system's logic levels.
Part Context
The MP2735 belongs to MPS's family of low-voltage analog switches designed for portable and automotive applications. It complements other MP27xx series devices offering similar switching capabilities with varying channel counts. The DQG package designation indicates a specific thermal and mechanical profile within the QFN family.
Replacement Considerations
The MP2736DQG-LF-Z is a related dual SPDT switch from the same manufacturer. Verify pin compatibility and electrical parameter differences before substitution. Other generic SPDT switches may require level shifting or offer higher on-resistance.
