Overview
The ADG431BNZ, produced by Analog Devices Inc., is a monolithic CMOS device that features four independently selectable single-pole single-throw (SPST) switches. Designed on an enhanced LC2MOS process, this component offers low power dissipation, high switching speed, and low on-resistance. The switches are controlled by digital inputs, with the ADG431 switches turning on with a logic low on the appropriate control input. This device is ideal for applications requiring high signal integrity and minimal power consumption.
