MAX4521ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521ESE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. The device features four normally closed switches with a maximum on-resistance of 100Ω and an on-resistance match between channels of 4Ω max. It provides rail-to-rail analog signal handling, off-leakage current of 1nA at +25°C, and 2kV ESD protection per Method 3015.7. The component is housed in a 16-pin Narrow SO package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before integration. Cross-reference part numbers with authorized distributors to validate authenticity and traceability. Confirm RoHS compliance status through verified datasheets prior to procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits that require multiple independent signal paths controlled by standard logic levels. Verify that the system's analog signals remain within the defined V+ and V- limits to prevent internal diode conduction. Consider the on-resistance flatness specifications if signal linearity is critical for the application environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4521/MAX4522/MAX4523 family of quad analog switches. While the MAX4521 utilizes normally closed contacts, the MAX4522 offers normally open configurations, and the MAX4523 combines both types. All variants share identical electrical characteristics and pinouts, differing only in the default state of the internal switches.
