MAX4623CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4623CSE is a dual, high-speed analog switch featuring two double-pole/single-throw (DPST) normally open channels. It operates from a single positive supply (+4.5V to +36V) or bipolar supplies (±4.5V to ±18V). The device guarantees a low on-resistance of 5Ω maximum and maintains channel-to-channel matching within 0.5Ω. Key electrical parameters include turn-on time under 250ns, turn-off time under 200ns, off-leakage current below 5nA at +85°C, and charge injection of 480pC. It utilizes a 16-pin Narrow SOIC package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range and 16-pin Narrow SOIC package. Confirm that the ordering information matches the manufacturer's latest datasheet revision to ensure compatibility with existing designs. Check for any pin-compatible alternatives if supply constraints exist.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent signal paths are required with low distortion. Ensure the analog signal range falls within the specified supply voltage limits. Consider the 5Ω on-resistance and leakage characteristics against system requirements for precision applications. Verify logic input levels match the control circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4623 is part of the MAX4621/MAX4622/MAX4623 family of precision analog switches. It serves as a pin-compatible replacement for legacy parts like the DG403. The family offers variations in pole-throw configurations while maintaining consistent performance metrics such as on-resistance and switching speed across all members.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include the DG403. Other family members like the MAX4621 and MAX4622 share similar electrical characteristics but differ in switch configuration.
