Overview
The ADG412BN, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable Single-Pole Single-Throw (SPST) switches. These switches are designed on an enhanced LC2MOS process, which ensures low power dissipation while providing high switching speed and low on-resistance. This makes the ADG412BN ideal for applications requiring high linearity and low distortion, particularly in audio and video signal switching.
