MAX4651ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4651ESE+ is a low-voltage, quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin SO package. It operates from a single +1.8V to +5.5V supply and features four normally closed switches. The device provides a maximum on-resistance of 7Ω at +3V and 4Ω at +5V, with an on-resistance matching of 0.2Ω maximum and flatness of 0.8Ω maximum over the signal range. It supports rail-to-rail analog signals, exhibits off-leakage current of 0.1nA at +25°C, and includes TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official datasheet specifications. Confirm the package type matches the 16-pin SO format and ensure the part number suffix corresponds to the standard operating temperature range. Cross-reference the ordering information to validate the specific variant details before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring low on-resistance and high channel matching within a single-supply environment. Ensure the control logic levels align with the specified input thresholds for reliable switching. Consider the thermal dissipation capabilities relative to the continuous current ratings when designing the PCB layout for optimal performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4651/MAX4652/MAX4653 family of low-voltage analog switches. While the MAX4652 offers normally open configurations and the MAX4653 combines both types, the MAX4651 specifically provides four normally closed channels. All variants share identical electrical characteristics and package options, differing only in their internal switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4652ESE+ and MAX4653ESE+. Verify that the alternative part's switch configuration (normally open or mixed) aligns with the circuit requirements, as these variants are electrically equivalent but functionally distinct regarding default states.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance flatness specification?

The on-resistance flatness is specified as a maximum of 0.8Ω at +5V and 2.5Ω at +3V over the entire analog signal range.

How does the MAX4651 differ from the MAX4652?

The MAX4651 contains four normally closed (NC) switches, whereas the MAX4652 contains four normally open (NO) switches. Both share identical electrical parameters and pinouts.
