MAX4745HELB+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4745HELB+ is a low-voltage, dual SPDT analog switch designed for audio applications. It operates from a single +1.8V to +5.5V supply and supports negative signal throughput down to VCC - 5.5V. The device features a typical on-resistance of 0.6Ω with a maximum channel-to-channel matching of 0.1Ω. It includes an enable input (EN) for high-impedance mode and internal protection against voltages applied to COM_ when VCC = 0V. Packaged in a 10-pin µDFN (2mm x 2mm), it operates over the -40°C to +85°C temperature range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the top marking code '+AAI' against the ordering information table. Confirm the package type is 10-pin µDFN and ensure the lead-free designation '+' is present. Cross-reference the part number suffix 'ELB+' with the manufacturer's official documentation to validate the specific configuration and protection features.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for dual-channel audio switching requiring negative rail capability. The MAX4745 variant uses two independent control bits, whereas the H-series utilizes a single control bit and an enable pin. Ensure the application requires the specific protection features available in the H-series variants for power sequencing robustness.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4744/MAX4745 family of low-voltage, dual SPDT audio switches. The 'H' suffix indicates the inclusion of an enable input and COM_ protection. The 'E' denotes the extended temperature range (-40°C to +85°C). The 'L' specifies the 10-pin µDFN package, and 'B+' indicates the tape-and-reel packaging format.
