MAX4523EGE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523EGE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch in a 16-pin QFN package. It integrates two normally closed and two normally open switches capable of handling rail-to-rail analog signals. The device operates from dual supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include an on-resistance of up to 100Ω, on-resistance flatness of 12Ω maximum, and off-leakage current of 1nA at +25°C. Logic inputs are TTL/CMOS compatible with thresholds of +0.8V and +2.4V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer markings against the official datasheet specifications. Ensure the ordering suffix matches the required temperature grade and packaging format. Confirm that the exposed pad connection requirements align with your PCB layout design to maintain proper thermal and electrical performance.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a mix of normally open and normally closed channels is required within a single package. Consider the specific on-resistance limits at your operating voltage and temperature. Evaluate the package thermal dissipation capabilities if driving significant currents through the analog switches.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX452x family of quad SPST analog switches. It shares the same pinout and core architecture as the MAX4521 and MAX4522, differing primarily in the internal configuration of the switch contacts. The EGE suffix indicates an industrial temperature range and a specific surface-mount package type.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements include the MAX4521EGE+T and MAX4522EGE+T, which share identical pinouts but offer different switch contact configurations. Verify that any substitute maintains the required voltage ratings and leakage characteristics for your specific application.
