Overview
The ADG779BKSZ-R2, produced by Analog Devices Inc., is a monolithic CMOS SPDT (single-pole, double-throw) switch designed on a submicron process. This switch is notable for its low power dissipation, high switching speed, low on-resistance, and low leakage currents. It operates from a single supply range of 1.8 V to 5.5 V, making it ideal for use in battery-powered instruments and with the new generation of DACs and ADCs from Analog Devices.
