MP2736DQG-LF-Z - 0.45 Ohm Dual SPDT Analog Switch | MPS
料号： MP2736DQG-LF-Z ✓ 量产中MP2736DQG-LF-Z 概述
The MP2736 combines two independently controlled SPDT switches in one IC. Its monolithic CMOS construction supports low power consumption, high switching speed, low on-resistance, and small package size. The manufacturer identifies the MP2735/MP2736 family as suitable for portable and battery-power applications where analog signal routing must be compact and power efficient.
The MP2736 uses an EN control input. According to the manufacturer datasheet information, all switches are placed in a high-impedance state when EN is high. This global enable behavior provides a defined off condition for both SPDT channels and can simplify system-level control when analog paths must be isolated. The dual SPDT arrangement supports selecting one of two signal sources per channel or routing a signal to one of two destinations, depending on the surrounding circuit topology.
The 450 mOhm on-resistance specification is the key low-voltage analog switching parameter identified in the verified distributor listings. Lower on-resistance helps reduce signal attenuation and improves source-to-load drive capability, while the 1.65 V to 5.5 V operating range allows operation from a single low-voltage supply. The 10-QFN package is particularly useful in portable equipment where board area is constrained. The -Z ordering suffix is supplied in tape-and-reel packaging according to distributor product information.
Typical applications include battery-powered sensor interfaces, portable measurement systems, audio routing, communication equipment, and compact analog signal-conditioning circuits. The EN pin can be used for power-down or signal-isolation control. Designers should verify the exact pin names, logic levels, switch configuration, and timing behavior against the MP2736 datasheet before finalizing a PCB layout.
This page combines the verified manufacturer and distributor information with practical selection guidance, package details, and design considerations. It is intended to help engineers identify whether the MP2736DQG-LF-Z is suitable for a low-voltage analog-routing design and to distinguish it from unrelated switch functions or package-incompatible alternatives.

典型应用
MP2736DQG-LF-Z 适用于 6 应用s: Battery-Powered Sensor Interface, Portable Audio Signal Routing, Portable Test and Measurement, Communication Equipment Signal Multiplexing, Low-Voltage Data Acquisition, Industrial Control and Automation.
Battery-Powered Sensor Interface
The MP2736DQG-LF-Z fits battery-powered sensor interfaces because its 1.65 V to 5.5 V operating range supports common low-voltage rails and its two SPDT circuits can route sensor signals through selectable analog paths. The 450 mOhm on-resistance limits signal attenuation when switching between a sensor and measurement circuitry. Its shared EN input also allows both paths to enter a high-impedance state when disabled, helping isolate the sensor front end during idle periods. The 1.4 mm by 1.8 mm 10-QFN package conserves board area in compact instrumentation. Confirm the exact switch topology and pin assignments in the manufacturer datasheet before assigning the source and destination nodes.
推荐
Portable Audio Signal Routing
The MP2736DQG-LF-Z can support compact audio-signal routing in portable equipment where two SPDT paths are needed in a small footprint. Its 450 mOhm on-resistance is well suited to low-impedance analog routing, and the 1.65 V to 5.5 V supply range can align with portable-device rails. The EN pin provides a common shutdown state in which both switches are high impedance, helping prevent unintended audio-path activity. Actual signal integrity depends on the source and load impedances, switch capacitance, and PCB routing, none of which were supplied in the verified excerpts. The manufacturer datasheet should be consulted for charge injection, off-isolation, switching time, and distortion-related information.
推荐
Portable Test and Measurement
For portable test and measurement equipment, the MP2736DQG-LF-Z offers two configurable SPDT channels in a compact 10-QFN package. The switches can alternate measurement paths, connect a source to one of two loads, or provide isolation between instrument sections. Their 450 mOhm on-resistance helps preserve low-level analog signals when the external circuit impedance is sufficiently high. The 1.65 V to 5.5 V operating range supports low-voltage battery-powered instruments, while EN gives the instrument a convenient common disable state. For high-accuracy or high-frequency designs, engineers must still validate charge injection, off-isolation, capacitance, bandwidth, and timing from the full manufacturer datasheet before final schematic sign-off.
推荐
Communication Equipment Signal Multiplexing
The MP2736DQG-LF-Z is applicable to compact communication equipment that requires analog routing at low supply voltage. Its two 2:1 SPDT circuits provide flexible switching for transmit, receive, test, or isolation paths, and the 450 mOhm on-resistance reduces insertion loss relative to higher-resistance switch implementations. The common EN control can isolate both channels together during mode changes, while the small 10-QFN package supports high-density layouts. For RF signals, engineers should verify that the switch's frequency range, capacitance, off-isolation, and insertion loss satisfy the system requirements; those parameters were not present in the verified excerpts and must be checked in the manufacturer datasheet.
推荐
Low-Voltage Data Acquisition
The MP2736DQG-LF-Z can route signals in a low-voltage data-acquisition front end where two selectable analog paths are needed per switch channel. Its 1.65 V to 5.5 V operating range permits operation from compact sensor and mixed-signal rails, while 450 mOhm on-resistance helps minimize loading of high-impedance acquisition nodes. The shared EN input allows the acquisition path to be disabled together, which may help control settling behavior or isolate external inputs. The small 10-QFN footprint also leaves room for converters, interface ICs, and local decoupling. Verify the switch's capacitance, charge injection, leakage, and settling specifications in the MP2736 datasheet, particularly when driving precision or high-speed ADC inputs.
推荐
Industrial Control and Automation
The MP2736DQG-LF-Z is suitable for low-voltage control and automation boards that need to select or isolate analog signals in a compact area. Its two SPDT channels can route sensor outputs, control references, or monitor signals, and the 450 mOhm on-resistance reduces voltage loss in low-voltage circuits. The EN pin supports coordinated isolation during maintenance or fault states, while the 1.65 V to 5.5 V range permits use with common low-voltage industrial rails. Industrial suitability, operating-temperature limits, ESD rating, and lifecycle status were not supplied in the verified excerpts, so qualification for a specific production environment requires review of the full datasheet and reliability documentation.

设计说明
Route the switched analog nodes as short, direct traces and place the device close to the signal source and destination. Because the MP2736DQG-LF-Z uses a compact 10-QFN package, preserve solder-mask and copper-pour symmetry to avoid assembly defects. Keep high-impedance control and sensitive analog traces separate from noisy power paths where practical. Confirm the exposed-pad or thermal-pad requirements against the package drawing before finalizing the footprint.
Provide a low-impedance bypass connection from the supply pin to ground and place it close to the MP2736DQG-LF-Z. The exact capacitor value and whether the device requires a specific charge-pump or supply arrangement were not included in the verified excerpts, so use the manufacturer recommended circuit and layout. Avoid placing the analog routing node beneath the switching IC when a quieter layout is possible. Validate supply current and power-up behavior in the final operating state.
Do not treat a shared package family as proof of complete interchangeability. For MP2736DQG-LF-P, verify the exact pinout, enable polarity, switch configuration, exposed-pad connection, ordering code, and tape-and-reel orientation. The EN input holds all switches at high impedance when high, so a mistaken logic assumption can interrupt both analog paths. Also account for switch charge injection, capacitance, and off-isolation when precision or high-speed signals are involved.
