MAX4968CCM+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4968CCM+ is a 16-channel, high-linearity, high-voltage, bidirectional SPST analog switch manufactured by Analog Devices Inc./Maxim Integrated. It utilizes HVCMOS technology to control high-voltage analog signals with low-voltage logic. The device operates with a VDD supply of +2.37V to +5.5V, a VPP positive supply of +9.5V to +10.5V (typical +10V), and a VNN negative supply of -160V to 0V. It features a typical on-resistance of 18Ω (max 34Ω) and supports an extended input range up to 210VP-P. The component is housed in a 48-pin LQFP package and functions over an operating temperature range of -40°C to +85°C.

• Nondestructive Testing (NDT)
• Industrial Ultrasound Imaging
• Printers

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CCM+' against official manufacturer documentation to confirm pinout and RoHS compliance status. Confirm that the required VPP supply voltage aligns with the standard +10V specification rather than high-voltage variants requiring +100V. Ensure the design accommodates the 48-pin LQFP thermal requirements within the specified temperature limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage switching is required without complex power sequencing. The MAX4968A variant includes integrated bleed resistors; verify if the standard MAX4968 configuration meets load discharge needs. Ensure the application signal frequency falls within the supported bandwidth ranges and that the logic levels match the VDD supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4968 family of high-voltage analog switches. It is pin-to-pin compatible with the MAX14802 and Supertex HV2601, though these alternatives typically require a higher +100V VPP supply. The MAX4968 series simplifies system design by allowing shared negative voltage supplies with transmitters.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX14802 and Supertex HV2601 are confirmed pin-compatible replacements, provided the system can support the higher +100V VPP supply voltage requirement associated with those parts.
