MAX4621ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4621ESE is a dual, high-speed analog switch in a 16-pin Narrow SO package. It features two single-pole/single-throw (SPST) normally open channels with a maximum on-resistance of 5Ω and guaranteed channel matching within 0.5Ω. The device operates from a single supply (+4.5V to +36V) or bipolar supplies (±4.5V to ±18V). Key electrical parameters include turn-on time under 250ns, turn-off time under 200ns, off-leakage current below 5nA at +85°C, and continuous switch current up to 100mA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Low on-resistance with guaranteed flatness over the full analog signal range
• TTL/CMOS logic input compatibility for direct interfacing
• Rail-to-rail analog signal handling capability across wide supply voltages

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing in communication systems
• Data-acquisition systems requiring low-distortion switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature range. Confirm the 'SE' designation corresponds to the 16-pin Narrow SOIC package. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer's ordering information to validate the exact part number configuration before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise channel matching are critical. The 5Ω on-resistance ensures minimal signal attenuation. Verify that the required voltage swing fits within the single or bipolar supply limits. Consider the 100mA continuous current rating for load requirements. Ensure the logic input levels match the system's control voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX462x family of precision analog switches. It serves as a pin-compatible replacement for legacy parts like the DG401. The MAX4621 specifically provides dual SPST functionality, distinguishing it from the DPST MAX4623 and the SPDT MAX4622 within the same series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4621ESE is a direct pin-compatible replacement for the DG401. Designers upgrading from mechanical relays or older CMOS switches should verify that the new on-resistance and leakage specifications meet the application's performance thresholds.
