MAX4523ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523ESE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two normally closed and two normally open switches within a 16-pin Narrow SO package. The device operates on dual supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include an on-resistance of 100Ω maximum, matched to 4Ω maximum across channels, with flatness of 12Ω maximum. Off-leakage current is specified at 1nA at +25°C and 10nA at +85°C. Logic inputs are TTL/CMOS compatible, and the component supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Offers mixed signal routing capabilities with two normally closed and two normally open SPST switches in a single package.
• Provides rail-to-rail analog signal handling capability over the full specified supply voltage range.
• Ensures high channel matching and signal integrity through tightly controlled on-resistance flatness and inter-channel matching specifications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment requiring low power consumption
• Data acquisition systems needing precise signal switching
• Audio signal routing applications
• Test and measurement instrumentation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ESE corresponds to the required 16-pin Narrow SO package and industrial temperature grade (-40°C to +85°C). Confirm that the mixed NC/NO configuration aligns with circuit requirements, as other variants like MAX4521 or MAX4522 offer different switch states. Ensure compatibility with existing PCB footprints for the SOIC-Narrow form factor during procurement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4523ESE+ when a combination of normally closed and normally open paths is necessary within a single quad-switch package. Consider the 100Ω on-resistance limit and 1nA leakage characteristics against system signal integrity requirements. Verify that the TTL/CMOS logic thresholds meet the driving interface standards, particularly if operating near the lower voltage limits of the single-supply range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. While sharing identical pinouts and core CMOS technology, the MAX4523 is distinct due to its mixed switch state configuration. It complements the all-normally-closed MAX4521 and all-normally-open MAX4522, providing design flexibility for complex signal routing topologies without requiring multiple discrete components.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same package include the MAX4521CSE+ and MAX4522CSE+, though their switch states differ. For mixed NC/NO configurations, no direct pin-compatible replacement with identical logic states is listed in the standard ordering information. Designers must verify if the specific NC/NO assignment can be accommodated by alternative part numbers or if circuit redesign is necessary.
