MAX4519CPD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4519CPD is a precision, monolithic CMOS analog multiplexer featuring dual 2-channel configuration in a 14-pin Plastic DIP package. It operates with single +2.7V to +15V or bipolar ±2.7V to ±8V supplies. Key electrical parameters include channel on-resistance (RON) of 60Ω to 100Ω at ±5V and 150Ω to 225Ω at +5V single supply. On-resistance matching between channels (ΔRON) is guaranteed within 4Ω to 10Ω. The device exhibits NO-off leakage current less than 2nA at +85°C and charge injection under 5pC. Switching speeds feature transition times under 250ns and enable turn-on/off times up to 275ns.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed low on-resistance matching between channels for signal integrity
• Rail-to-rail signal handling capability across the full supply range
• TTL/CMOS-logic compatible inputs with reduced input loading
• Extremely low power consumption suitable for battery-operated systems

Analog Switches, Multiplexers, Demultiplexers Applications

• Sample-and-Hold Circuits
• Automatic Test Equipment
• Audio Signal Routing
• Low-Voltage Data-Acquisition Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPD corresponds to the 14-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm that the ordering code matches the exact pinout and logic compatibility requirements for the target design. Ensure the component meets RoHS compliance standards if required by the manufacturing process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 2-channel topology is required rather than a 4-channel arrangement. Consider the RON flatness and leakage specifications relative to the operating voltage. Verify that the 14-pin DIP footprint fits the PCB layout constraints compared to SO or QSOP alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4518/MAX4519 family of precision analog multiplexers. While the MAX4518 provides four independent channels, the MAX4519 offers two dual switches. Both share identical fabrication processes and electrical characteristics, differing primarily in channel count and pin assignments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4518CPD serves as a functional substitute if four channels are acceptable instead of two. Other package variants like MAX4519CSD (SOIC) provide equivalent electrical performance with different physical footprints.
