MAX4521EEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521EEE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches housed in a 16-pin QSOP 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, on-resistance flatness of 12Ω max, and channel-to-channel matching of 4Ω max. Off-leakage current is specified at 1nA at +25°C and 10nA at +85°C. Switching times are typically 80ns for turn-on and 30ns for turn-off under standard conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EEE' corresponds to the extended temperature range (-40°C to +85°C) and QSOP package type as documented in the official Maxim Integrated datasheet. Confirm that the component meets the required voltage and leakage specifications for the intended application environment before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4521EEE when a normally closed switch configuration is required for the application. Ensure the system operates within the specified ±2V to ±6V dual supply or +2V to +12V single supply ranges. Verify that the 100Ω maximum on-resistance and switching speeds meet the circuit performance requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. The MAX4521 variant specifically provides four normally closed switches, distinguishing it from the MAX4522 (normally open) and MAX4523 (mixed NC/NO) configurations within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other variants within the MAX4521 series such as MAX4521CEE or MAX4521ESE, provided they match the required temperature range and package dimensions. Cross-referencing pinouts and electrical characteristics with the official datasheet is essential for compatibility.
