MAX399CSE+ 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 SWITCH SP4T X 2 100OHM 16SOIC. Review the specifications below when checking this part for your BOM.
The MAX399CSE+ is a precision, monolithic CMOS analog multiplexer featuring two independent 4-to-1 channels in a 16-pin Narrow SOIC package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include an on-resistance of 100Ω maximum and channel matching within 6Ω. The device supports rail-to-rail signal handling, low charge injection (less than 5pC), and off-leakage current under 2.5nA at +85°C. Transition times are less than 250ns, with power consumption below 300µW.
Verify the specific suffix 'CSE+' against the official Analog Devices / Maxim Integrated datasheet to confirm the commercial temperature range (-40°C to +85°C) and the narrow SOIC-16 package type. Ensure that the ordering information matches the exact part number required for your design specifications before finalizing procurement.
Select this component when dual 4-channel multiplexing is required with low on-resistance and precise channel matching. It is suitable for applications needing compatibility with legacy DG408/DG409 footprints while offering improved performance characteristics such as lower leakage and faster switching speeds compared to older generations.
The MAX399CSE+ belongs to the MAX398/MAX399 family of precision analog multiplexers manufactured by Analog Devices / Maxim Integrated. This series is designed for low-voltage applications and offers robust electrostatic discharge protection exceeding 2000V. The CSE+ designation specifically indicates the commercial grade operating temperature range and surface-mount packaging.
Public confirmed substitutes include DG408, DG409, DG508A, and DG509A due to pin compatibility.
