MAX4521CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521CPE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed (NC) switches housed in a 16-pin Plastic DIP package with an operating temperature range of 0°C to +70°C. The device supports dual power 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 between channels of 4Ω max, and an on-resistance flatness of 12Ω max. Off-leakage current is specified at 1nA at +25°C and 10nA at +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Supports rail-to-rail analog signal handling across the full supply voltage range.
• Features TTL/CMOS-compatible digital inputs for direct logic interfacing.
• Provides high off-isolation and low crosstalk for signal integrity.

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment
• Data acquisition systems
• Test equipment
• Avionics
• Audio signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component revision level against the latest datasheet specifications before integration. Confirm that the 16-pin PDIP package dimensions align with the target PCB footprint. Ensure the supply voltage constraints are strictly observed to prevent exceeding absolute maximum ratings during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed SPST configuration is required for low-voltage applications. Compare the 100Ω on-resistance against system requirements; consider the MAX4522 if normally open switching is needed instead. Verify that the ±2V to ±6V dual supply or +2V to +12V single supply options fit the design power budget.

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). All variants share identical pinouts and electrical characteristics except for the switch state logic.
