MAX4968BEXB+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4968BEXB+T is a 16-channel, high-linearity, high-voltage bidirectional SPST analog switch in a 64-bump BGA package. It operates with a logic supply of +2.37V to +5.5V, a positive supply of +10V to +12.5V, and a negative supply of 0V to -200V. The device features an on-resistance of 18Ω typical (34Ω max) and supports an extended input range up to 210VP-P. Small-signal bandwidth reaches 30MHz at CLOAD = 200pF, while large-signal bandwidth reaches 50MHz. Turn-on time is 5µs maximum and turn-off time is 3.5µs maximum. Operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Optimized for high-channel-count systems using a compact 64-bump BGA package.
• Ensures high image quality through true linear switching with guaranteed RON flatness across the entire input range.
• Eliminates the need for dedicated high-voltage supplies by sharing the negative voltage with transmitters.
• Features asynchronous set/clear inputs to program all switches simultaneously without requiring SPI.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure that the required negative voltage supply capabilities align with system design constraints before procurement. Confirm availability through authorized distributors as stock levels may vary.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring control of high-voltage analog signals via low-voltage logic. Consider the MAX4968CEXB+ variant if integrated bleed resistors are necessary for discharging capacitive loads. Verify that the serial interface timing requirements match the host controller's clock speeds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4968 family of high-voltage analog switches manufactured by Analog Devices / Maxim Integrated. The series utilizes HVCMOS technology to combine high-voltage bilateral MOS switches with low-power CMOS logic. The BGA package variant provides a space-efficient solution for dense channel configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4968CEXB+ serves as a direct functional substitute within the same package, distinguished only by the inclusion of integrated 40kΩ bleed resistors on each switch terminal.
