MAX4621CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4621CSE is a dual, high-speed analog switch featuring two single-pole/single-throw (SPST) normally open channels in a 16-pin Narrow SO package. It operates from a single supply of +4.5V to +36V or bipolar supplies of ±4.5V to ±18V. The device guarantees an on-resistance of 5Ω maximum with a channel-to-channel match of 0.5Ω maximum and flatness of 0.7Ω maximum over the full signal range. Switching times are less than 250ns for turn-on and 200ns for turn-off. Leakage current is less than 500pA at +25°C and less than 5nA at +85°C. Operating temperature range is 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin Narrow SOIC package configuration. Confirm that the component meets RoHS compliance standards as indicated by the '+' designation in related part numbers within the same family. Ensure the ordering information matches the required voltage and leakage specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and fast switching are required in place of mechanical relays. The MAX4621CSE is suitable for applications needing rail-to-rail signal handling and CMOS logic compatibility. Consider the MAX4622E or MAX4623E variants if extended temperature ranges (-40°C to +85°C) or different switch configurations (SPDT or DPST) are necessary for the system design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4621CSE belongs to the MAX4621/MAX4622/MAX4623 family of precision, dual, high-speed analog switches manufactured by Analog Devices Inc./Maxim Integrated. This series is designed to offer improved performance over legacy parts like the DG401 while maintaining pin compatibility. The C suffix denotes the commercial temperature grade, distinguishing it from the E suffix which covers the industrial temperature range.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4621CSE serves as a direct pin-compatible replacement for the DG401. Designers upgrading from older discrete solutions or legacy ICs should verify that the new supply voltages and logic levels are compatible with the existing circuit board layout and control signals.
