MAX4968CEXB+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4968CEXB+ is a high-voltage analog switch IC featuring sixteen independent SPST channels in a CTBGA-64 package. It operates on a single supply voltage ranging from 2.37 V to 5.5 V, or dual supplies between -200 V/10 V and 0 V/12.5 V. The device exhibits a maximum on-resistance of 34 Ohms with a 30 MHz bandwidth. Switching times are limited to 5 µs for turn-on and 3.5 µs for turn-off. It functions within an industrial temperature range of -40°C to +85°C and consumes a maximum supply current of 50 µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure the ordering part number matches the required thermal and mechanical specifications for the target PCB layout. Cross-reference the manufacturer's latest datasheet revision to validate compliance with current environmental standards before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring high-voltage handling capabilities alongside multi-channel switching density. Evaluate the 34 Ohm on-resistance against the load requirements to ensure acceptable signal attenuation. Confirm that the 5 µs switching speed aligns with the system's timing constraints and that the CTBGA-64 footprint fits the available board space.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4968 family of high-voltage CMOS analog switches designed by Maxim Integrated, now part of Analog Devices. The series addresses the need for robust signal routing in environments where standard low-voltage switches cannot withstand the required potential differences. The CEXB variant specifically denotes the surface-mount BGA packaging option.
