MAX4659EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4659EUA+ is a single-channel, single-pole/double-throw (SPDT) CMOS analog switch designed for medium-voltage applications. It features a maximum on-resistance of 25 ohms at ±15V supplies and supports continuous currents up to 75mA with peak capabilities of 150mA. The device operates within a supply range of +9V to +40V for single-supply or ±4.5V to ±20V for dual-supply configurations. Key electrical parameters include an off-leakage current of 1nA maximum, a charge injection of 1.5pC, and a -3dB bandwidth of 225MHz. It is housed in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-current handling capability suitable for switching loads as low as 50 ohms
• TTL/CMOS compatible logic control without requiring a separate VL supply
• Rail-to-rail signal handling across the full power-supply range
• Low power consumption of approximately 3mW regardless of switch state

Analog Switches, Multiplexers, Demultiplexers Applications

• Relay replacement in systems requiring high speed and long life cycles
• Audio signal routing and audio system interconnects
• Test equipment and redundant/backup system switching
• Communication systems including xDSL modems and PBX/PABX networks

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The 'EUA' designation indicates an industrial temperature range (-40°C to +85°C) and an 8-pin µMAX package. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high continuous current switching is required alongside low on-resistance. Ensure the application voltage does not exceed the absolute maximum ratings of ±44V between V+ and GND. Consider thermal dissipation limits if operating near the maximum current ratings, as power dissipation varies significantly between package types.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4659/MAX4660 family of high-current CMOS analog switches. While pin-compatible with devices like the DG419 and MAX319, it offers superior current handling. The MAX4660 variant provides higher continuous current ratings but requires an exposed paddle for thermal management, whereas the MAX4659 does not mandate this feature.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include the DG419 and MAX319. Verify that substitute components meet the specific 75mA continuous current requirement of the MAX4659, as some generic SPDT switches may only support lower current levels.
