MAX4523EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523EUE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It features two normally closed and two normally open switches within a 16-pin TSSOP package. The device operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include a maximum on-resistance of 100Ω, an on-resistance match of 4Ω max, and flatness of 12Ω max over the signal range. Off-leakage current is specified at 1nA at +25°C and 10nA at +85°C. The component supports rail-to-rail analog signals and includes TTL/CMOS-compatible digital inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EUE corresponds to the required temperature range and package type before procurement. Confirm that the exposed pad connection requirements align with the PCB layout design. Ensure compatibility with existing logic voltage levels, as thresholds vary slightly with supply voltage changes. Cross-reference the manufacturer's latest documentation for any updates to pin configurations or absolute maximum ratings.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed switching functions is required in a single package. Consider the on-resistance flatness and leakage specifications for high-precision applications. Evaluate the operating temperature range against environmental conditions. Verify that the supply voltage constraints fit within the system's power budget and signal swing requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4523EUE+ belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. While the MAX4521 provides four normally closed switches and the MAX4522 offers four normally open switches, the MAX4523 combines two of each. This family shares common electrical characteristics such as low power consumption and CMOS logic compatibility, differing primarily in the internal switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include MAX4521EUE+ and MAX4522EUE+. These parts share identical packages and electrical specifications but differ in switch configuration. Verify that the alternative part's NC/NO arrangement meets the circuit design requirements before substitution.
