MAX4612CUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4612CUD+ is a low-voltage, quad single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates two normally open and two normally closed switches within a 14-pin TSSOP package. The device operates from a single +2V to +12V supply with maximum on-resistance of 100Ω at +5V and 46Ω at +12V. On-resistance matching between channels is guaranteed to 4Ω max, with flatness over the signal range at 18Ω max. Off-leakage current is limited to 1nA at +25°C and 2nA at +85°C. Turn-on time reaches 65ns and turn-off time 28ns at +5V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required temperature range and packaging type. Ensure compliance with RoHS standards as indicated by the plus sign in the part number. Cross-reference the datasheet revision history for any recent updates to electrical characteristics or pin configurations before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing low-voltage systems requiring mixed normally open and normally closed switching functions. Verify that the single-supply voltage range aligns with the system's power architecture. Consider the thermal dissipation limits in the TSSOP package if operating near maximum ratings. Evaluate the leakage current specifications against the sensitivity requirements of the connected analog signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. While the MAX4610 offers four normally open switches and the MAX4611 provides four normally closed switches, the MAX4612 combines two of each configuration. All variants share identical pinouts and electrical characteristics, differing only in the internal switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4612CSD+ serves as a direct replacement using a narrow SOIC package. For extended temperature ranges, the MAX4612EUD+ covers -40°C to +85°C. The MAX4612CPD+ offers a plastic DIP alternative. Ensure pin compatibility and electrical parameter alignment when substituting these variants.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4610, MAX4611, and MAX4612?
