Overview
The ADG441BNZ, 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 device 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. The ADG441BNZ is suitable for various applications requiring high performance and reliability in analog signal switching.
