Overview
The ADG781BCPZ-REEL7 is a monolithic CMOS device produced by Analog Devices Inc., featuring four independently selectable single-pole single-throw (SPST) switches. These switches are designed using an advanced submicron process, which ensures low power dissipation, high switching speed, low on-resistance, low leakage currents, and high bandwidth. The device operates from a single supply voltage ranging from +1.8 V to +5.5 V, making it suitable for use in battery-powered instruments and with modern DACs and ADCs.
