MP2736DQG-LF-P - 450mΩ Dual SPDT Analog Switch | MPS
MPN: MP2736DQG-LF-P ✓ ActiveMP2736DQG-LF-P Overview
An analog switch is an integrated semiconductor device that routes signals between circuit nodes under digital control. The SPDT topology connects one common terminal to one of two selectable terminals, allowing one signal source to be steered between two destinations. A dual SPDT switch contains two independently controlled 2:1 paths. Within the device hierarchy, the MP2736DQG-LF-P is an analog switch IC, a member of the broader interface IC category used for signal routing and multiplexing.
Key features include a low on-resistance of 450 mΩ, a single-supply operating range of 1.65 V to 5.5 V, and a specified operating temperature range from -40°C to +85°C. The MP2736 family combines low power consumption, high switching speed, low on-resistance, and a small package. Its two switching circuits and common enable architecture suit compact portable and battery-powered equipment where PCB area and supply current are important constraints.
The MP2736 is implemented as a monolithic CMOS analog switch, allowing low-voltage operation and efficient signal routing. Switching times of 35 ns and 36 ns are specified in the verified product information, supporting applications that cannot tolerate lengthy transition intervals. The available bandwidth reaches 50 MHz, while the 130 pF value identifies the relevant capacitance specification from the supplied source data. Because the switch is bidirectional, it can route signals in either direction when the electrical operating conditions remain within the device limits.
Typical uses include battery-powered audio routing, portable test and measurement interfaces, communication-signal multiplexing, sensor-path selection, and general analog signal switching. The 10-QFN package provides a practical footprint for dense portable systems, while the 1.65 V to 5.5 V range covers common low-voltage rails. In each case, the design must account for signal amplitude, switching duration, off-state behavior, and the exact enable polarity and timing required by the application.
A key design consideration is that low on-resistance does not eliminate all analog-switch limitations. Board leakage, connector resistance, and trace resistance can dominate a 450 mΩ path, while capacitive loading can influence switching performance. Designers should minimize sensitive traces, use a continuous ground reference, and verify signal integrity with the actual source impedance, load, supply voltage, and enable sequence before production release.

Typical Applications
MP2736DQG-LF-P is suitable for 6 applications: Portable Audio Signal Routing, Battery-Powered Sensor Multiplexing, Communication Signal Multiplexing, Portable Test and Measurement, Battery-Charging and Power-Path Selection, Consumer and Wearable Signal Routing.
Portable Audio Signal Routing
The MP2736DQG-LF-P is suitable for routing low-voltage audio signals in portable equipment because its dual-SPDT topology provides two selectable 2:1 paths while its 450 mΩ on-resistance limits avoidable signal loss. The 1.65 V to 5.5 V supply range fits low-voltage portable systems, and the 10-QFN package measuring 1.4 mm by 1.8 mm supports compact layouts. Its 35 ns and 36 ns switching times allow the control path to change routes quickly. Designers should still account for source impedance, connector resistance, and capacitive loading because total channel loss can exceed the switch on-resistance alone.
Battery-Powered Sensor Multiplexing
The MP2736DQG-LF-P can select between sensor or analog-signal paths in battery-powered equipment. Its two independent 2:1 switch circuits provide a compact way to route multiple sources without allocating a large discrete relay or redesigning the PCB. Operation from 1.65 V to 5.5 V covers common battery-derived rails, while the low 450 mΩ on-resistance helps preserve signal integrity in measurement paths. The manufacturer identifies low power, high speed, and small package size as central advantages for portable and battery applications.
Communication Signal Multiplexing
The MP2736DQG-LF-P is applicable when a compact system must route communication signals between two destinations. A dual-SPDT configuration allows each common path to be steered independently, and the specified 50 MHz bandwidth supports higher-frequency routing requirements. Its bidirectional channels can simplify signal-path orientation, while the 450 mΩ on-resistance keeps the device suitable for many low- to moderate-impedance analog nets. For RF or high-speed digital traffic, engineers must verify insertion loss, return loss, off impedance, and crosstalk using the complete board layout and connector model.
Portable Test and Measurement
The MP2736DQG-LF-P can be used in portable measurement equipment to connect a source to one of two instrument or fixture paths. Its dual-SPDT organization preserves PCB area compared with implementing two separate switch functions, and the 1.4 mm by 1.8 mm 10-QFN package supports dense front ends. The 35 ns and 36 ns switching times enable rapid path changes, while the 450 mΩ resistance is meaningful when driving high-impedance sensors but may require a lower-resistance switch for low-impedance loads.
Battery-Charging and Power-Path Selection
The MP2736DQG-LF-P may be used to select low-voltage analog or sensing paths in battery-charging systems where routing must operate from 1.65 V to 5.5 V. Its compact dual-SPDT design and bidirectional operation simplify channel assignment, and the fast 35 ns and 36 ns transition ratings support prompt control response. However, this part is an analog switch rather than a power MOSFET or charger, so it should not be used to carry current beyond its published signal ratings. Actual current, voltage, and transient limits must be checked in the manufacturer datasheet.
Consumer and Wearable Signal Routing
The MP2736DQG-LF-P fits consumer and wearable designs that require multiple analog routes in a restricted PCB area. Its dual-SPDT architecture provides two 2:1 paths in one 10-QFN package, and the 1.65 V to 5.5 V operating range aligns with low-voltage portable rails. The manufacturer specifically identifies portable and battery-powered use cases and emphasizes low power, high speed, low on-resistance, and small package size. Layout should maintain short signal traces and an uninterrupted ground reference to minimize parasitic effects in sensitive wearable and mobile-device signal chains.

Key Differentiators
- Verified 100% parametric configuration match (vs MP2736DQG-LF-Z)
- Identical compact package footprint (vs MP2736DQG-LF-Z)
- Same low-voltage operating class (vs MP2736DQG-LF-Z)
Design Notes
Place the MP2736DQG-LF-P close to the source and destination pads whose signals are being routed. Keep each switched net short, provide a continuous ground reference beneath the QFN-10 footprint, and avoid sharing sensitive paths with fast digital or switching-supply return currents. Because the verified on-resistance is 450 mΩ, trace and connector resistance can become significant relative to the device contribution; use the complete resistive path when evaluating insertion loss.
Validate switched-channel settling with the real source impedance, load capacitance, cable or connector loading, and enable timing rather than relying only on the 35 ns and 36 ns switching-time figures. The device supports bidirectional routing, but signal amplitude and common-mode limits must remain within the manufacturer specifications. For the stated 50 MHz bandwidth, use controlled-impedance routing where applicable and measure insertion loss and crosstalk on the assembled PCB.
Do not treat MP2736DQG-LF-P as a general-purpose power switch without checking the published voltage, current, and transient limits. Its verified 450 mΩ on-resistance and glitch-free behavior describe analog signal switching, not the low resistance of a power MOSFET. Likewise, confirm the enable polarity and operating state from the manufacturer datasheet: the verified family documentation states that the switches are at high impedance when EN is high.
Operate the device from a supply within its specified 1.65 V to 5.5 V range and verify that supply transients remain within the manufacturer limits. Decouple the supply locally and route return current directly to the device ground reference. Because the supplied records do not include the power-supply rejection, quiescent-current, or maximum input-voltage values, those parameters must be checked in the official datasheet before final rail selection.
Compliance Information
The verified JLCPCB product record identifies the MP2736DQG-LF-P as RoHS compliant. No explicit REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements were present in the supplied data. AEC-Q100 is treated as not applicable because this product is an interface IC rather than an automotive-qualified device.
