MAX4968BEXB+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4968BEXB+ is a high-voltage, latchup-free analogue switch IC manufactured by Analog Devices Inc./Maxim Integrated. It integrates sixteen independent single-pole, single-throw (SPST) channels within a BGA-64 surface-mount package. The device supports dual supply voltages ranging from -200 V to 12.5 V and operates on a control supply between 2.37 V and 5.5 V. Key electrical specifications include a maximum on-resistance of 34 Ohms, a maximum operating time of 5 µs, and a maximum off-time of 3.5 µs. Power dissipation is rated at 1.97 W with a maximum supply current of 50 µA. The component functions across an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EXB against official datasheets to confirm the BGA-64 package type and tape-and-reel shipping configuration. Confirm RoHS compliance status through manufacturer documentation. Ensure design compatibility with the specified -200 V to 12.5 V dual supply requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits that require switching signals exceeding standard logic levels. The 16-channel density reduces board space compared to discrete solutions. Verify that the 34 Ohm on-resistance meets the signal attenuation limits of the application. Ensure the PCB layout accommodates the thermal dissipation capabilities required for the 1.97 W rating.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4968 family of high-voltage linear switches. Variants such as the MAX4968CEXB+T and MAX4968BEXB+ share similar functional architectures but differ in packaging or grade specifications. The MAX4968 series addresses the need for robust analog switching in environments where standard CMOS switches would fail due to voltage stress.
