MAX399CEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX399CEE+ is a precision, monolithic CMOS analog multiplexer featuring two independent 4:1 channels in a 16-pin QSOP package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include an on-resistance of 100Ω maximum at ±5V and 225Ω maximum at +5V single supply, with channel matching within 6Ω. The device offers low leakage (less than 2.5nA at +85°C), charge injection under 5pC, and transition times under 250ns. It supports rail-to-rail signal handling and provides ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin QSOP package configuration. Confirm that the ordering code matches the exact pinout and lead finish requirements for your PCB footprint. Ensure compatibility with existing design files before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-channel switching is required with low voltage operation. Verify that the single-supply or dual-supply configuration aligns with the system's power architecture. Consider the thermal dissipation limits if operating near the upper end of the specified temperature range or load current conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX398/MAX399 family of precision analog multiplexers. While the MAX398 provides eight channels in a single package, the MAX399 offers two separate four-channel switches. Both share identical fabrication processes and electrical characteristics, differing primarily in channel count and pin assignment.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX399CEE+ is directly pin-compatible with the DG409, DG509A, and other MAX399 variants such as MAX399EEE+. When substituting, verify that the alternative package type maintains the same pinout and that the replacement meets the required temperature and electrical specifications.
