MAX4503CPA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4503CPA is a low-voltage, dual-supply, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally open configuration and operates continuously with dual supplies between ±1V and ±6V. The device handles rail-to-rail analog signals with an off-leakage current of only 1nA at +25°C or 10nA at +85°C. It is housed in an 8-pin Plastic DIP package and supports an operating temperature range from 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual-supply operation capability ranging from ±1V to ±6V
• Guaranteed low off-leakage currents for signal isolation
• CMOS-logic compatible digital input architecture without ground pin
• Fast switching speed with guaranteed low charge injection

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment
• Audio and video signal routing
• Low-voltage data-acquisition systems
• Communications circuits
• PCMCIA cards

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CPA' corresponds to the 8-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the supply voltage limits align with your system design before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4503CPA when a normally open SPST switch is required for dual-supply applications. Compare on-resistance specifications against your signal integrity needs, as it varies with supply voltage. Consider the MAX4504 variant if a normally closed configuration is preferred instead. Verify logic level compatibility with your control circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4503CPA belongs to the MAX4503/MAX4504 family of low-voltage, dual-supply, SPST CMOS analog switches. This series is designed for applications requiring rail-to-rail signal handling and low leakage currents. The CP suffix indicates the commercial temperature grade, while the A denotes the PDIP package style within the broader product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4501 and MAX4502 are pin-for-pin equivalents designed for single-supply operation. For dual-supply replacements, consider other members of the MAX4503/MAX4504 family with different temperature grades or packages.
