MAX4522ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4522ESE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally open switches housed in a 16-pin Narrow SO package with an operating temperature range of -40°C to +85°C. The device supports dual supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include a maximum on-resistance of 100Ω, channel-to-channel matching of 4Ω max, and flatness of 12Ω max. Off-leakage current is specified at 1nA at +25°C and 10nA at +85°C. Logic inputs are TTL/CMOS compatible with thresholds of +0.8V and +2.4V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature grade. Ensure that the selected variant matches the required operational environment and pin configuration for the target application design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with low-voltage operation is required. Consider the MAX4521 or MAX4523 if normally closed contacts or mixed configurations are needed instead of the standard normally open topology provided by the MAX4522.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. The family shares identical electrical characteristics and pinouts, differing only in the internal logic state of the switches (normally open, normally closed, or mixed).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional equivalents within the same family include MAX4521CSE and MAX4523CSE for commercial temperature grades, or MAX4521ESE and MAX4523ESE for extended temperature ranges, depending on the required contact state.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between MAX4522 and MAX4521?

The MAX4522 contains four normally open (NO) switches, whereas the MAX4521 contains four normally closed (NC) switches. Both share identical electrical specifications and pinouts.

Is the MAX4522ESE suitable for single-supply operation?

Yes, the device operates from a single supply between +2V and +12V when the V- pin is connected to ground.

How does the MAX4522 handle signals exceeding the supply rails?

Internal reverse ESD-protection diodes clamp signals exceeding V+ or V-. Forward-diode current must be limited to the maximum rating during such events.
