MAX4657ESA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4657ESA is a single-channel, normally closed (NC) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a supply voltage range of 9V to 40V for single-supply configurations or ±4.5V to ±20V for dual-supply setups. The device features a maximum on-resistance of 10 Ohms and supports a DC switch current of 300 mA. Key electrical parameters include a maximum turn-on time of 200 ns and a maximum turn-off time of 100 ns. It is housed in an 8-SOIC surface-mount package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Normally closed signal path configuration for fail-safe applications
• High-current switching capability supporting up to 300 mA DC load
• Low on-resistance characteristic ensuring minimal signal attenuation

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in test and measurement equipment
• Data acquisition systems requiring normally closed states
• Industrial process control signal isolation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific datasheet revision prior to integration. Ensure packaging integrity matches the SOIC-8 tube format specified in official documentation. Validate that the ordering suffix corresponds exactly to the required pinout and electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switch is required rather than the standard normally open topology. Compare the 10 Ohm on-resistance against circuit impedance requirements to minimize insertion loss. Verify that the 9V minimum supply voltage aligns with available system rails, as lower voltage operation is not supported.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4655-MAX4658 family of high-current CMOS analog switches. The MAX4657 variant specifically provides the normally closed function, distinguishing it from the normally open MAX4655 and the complementary SPDT MAX4656. All members share similar electrical characteristics and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4655ESA+ serves as a functional substitute if a normally open configuration is acceptable. For dual-channel applications, the MAX4656ESA+ offers complementary switching capabilities within the same package footprint.
