MAX4669CSE+ is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC SW SPST-NO/NCX2 2.5OHM 16SOIC. Review the specifications below when checking this part for your BOM.
The MAX4669CSE+ is a dual SPST CMOS analog switch in a 16-pin Narrow SOIC package. It features a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω over the signal range. The device supports single supplies from +4.5V to +36V or dual supplies from ±4.5V to ±20V. It handles Rail-to-Rail signals, offers low off-leakage current (5nA max at +85°C), and guarantees break-before-make operation. Operating temperature ranges from 0°C to +70°C.
Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) against the datasheet ordering information. Confirm the 'E' variant availability if industrial temperature ratings are required. Ensure the Narrow SOIC package dimensions match the design footprint requirements before finalizing procurement.
Select this component for applications requiring low distortion and high reliability compared to mechanical relays. Verify that the 2.5Ω on-resistance meets the voltage drop requirements for the target load current. Ensure the supply voltage stays within the specified single or dual limits to maintain proper logic thresholds and signal integrity.
This part belongs to the MAX4667/MAX4668/MAX4669 family of dual analog switches. While the MAX4667 provides two normally closed switches and the MAX4668 provides two normally open switches, the MAX4669 combines one normally open and one normally closed switch to ensure break-before-make timing.
MAX4669ESE+
The primary difference is the operating temperature range. The MAX4669CSE+ operates from 0°C to +70°C, while the MAX4669ESE+ operates from -40°C to +85°C.
It guarantees break-before-make operation, ensuring that one switch opens before the other closes to prevent short circuits during state changes.
