MAX4537EEE/GH9

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4537EEE is a quad, single-pole single-throw normally-closed (SPST-NC) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single supply voltage ranging from 2V to 12V or dual supplies of ±2V to ±6V. The device features four independent channels with a maximum on-resistance of 100 Ohms and a channel-to-channel matching of 1 Ohm. Key electrical specifications include a maximum charge injection of 1pC, off-state leakage current of 1nA, and crosstalk of -75dB at 1MHz. Switching times are specified as 100ns for turn-on and 50ns for turn-off. It is housed in a 16-SOIC surface-mount package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and functional equivalence. Ensure the component meets RoHS3 compliance requirements if mandated by the design specification. Confirm the package type matches the intended PCB footprint before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed state is required for signal paths during power-down or inactive periods. The 100 Ohm on-resistance is suitable for general-purpose analog switching where lower resistance is not critical. Verify that the 12V single-supply limit aligns with the system voltage rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4536-MAX4539 family of low-power, high-speed analog switches. These devices are designed to provide reliable signal path management in mixed-signal environments. The MAX4537 variant specifically offers four normally-closed channels within the series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4537ESE+ is a verified equivalent offering identical functionality in a 16-SOIC package. Cross-reference the datasheet to ensure package dimensions and thermal characteristics match the existing design constraints.
