MAX4968ECM+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4968ECM+ is a 16-channel, high-linearity, high-voltage, bidirectional SPST analog switch manufactured by Analog Devices Inc./Maxim Integrated. It utilizes HVCMOS technology to combine high-voltage bilateral MOS switches with low-power CMOS logic. The device operates with a logic supply voltage (VDD) ranging from +2.37V to +5.5V and a negative supply voltage (VNN) from -200V to 0V. It features a typical on-resistance of 18Ω 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.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific part number matches the exact suffix requirements for your application. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering information aligns with the intended packaging format and lead time constraints provided by the supplier at the time of purchase.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4968ECM+ when a 16-channel configuration is required without integrated bleed resistors. Choose this variant over the MAX4968AECM+ if external discharge paths are preferred or unnecessary. Verify that the system's negative supply voltage falls within the specified operational limits to ensure proper signal transmission and device reliability.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4968ECM+ belongs to the MAX4968/MAX4968A family of 16-channel linear high-voltage analog switches. This series is designed for applications requiring high-voltage switching controlled by low-voltage signals. The ECM+ suffix indicates a lead-free/RoHS-compliant package in the 48-LQFP form factor, suitable for surface-mount assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4968ECM+ is pin-to-pin compatible with the MAX14802 and Supertex HV2601. These components share identical pinouts but differ in the required positive supply voltage level (VPP), which is typically +10V for the MAX4968ECM+ compared to higher voltages for the alternatives.
