MAX4623ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4623ESE+ 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, with channel matching within 0.5Ω and flatness over the full signal range. It supports rail-to-rail analog signal handling and maintains TTL/CMOS logic compatibility. Key electrical parameters include turn-on time under 250ns, turn-off time under 200ns, and off-leakage current below 5nA at +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual DPST configuration for simultaneous switching of two independent signal paths
• Low on-resistance with guaranteed channel matching and flatness across the signal range
• Rail-to-rail analog signal handling capability compatible with wide supply voltages
• TTL and CMOS logic input compatibility for direct interface with digital control systems

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing in communication systems
• Data-acquisition systems requiring precise signal switching
• Military radios and avionics applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) and 'SE' denotes the narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation prior to ordering. Ensure supply voltage sequencing adheres to absolute maximum ratings to prevent device damage during power-up.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4623ESE+ when a dual DPST switch topology is required rather than SPST or SPDT configurations. This part is suitable for applications demanding low distortion and high reliability compared to mechanical relays. Verify that the required analog signal range fits within the selected single or bipolar supply rails.

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 DG405. The E-series variants offer extended industrial temperature ranges compared to C-series parts, making them suitable for harsher operating environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include the DG405. Verify functional equivalence regarding on-resistance and leakage specifications before substitution.
