Overview
The ADG432BR, produced by Analog Devices Inc., is a monolithic CMOS device that comprises 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. Each switch conducts equally well in both directions when ON and has an input signal range that extends to the supplies. This makes the ADG432BR ideal for various applications requiring precise and efficient signal switching.
