Overview
The ADG452BRZ, 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. This makes it suitable for a variety of applications, including audio and video signal switching, relay replacement, and use in battery-powered systems. The device is TTL-/CMOS-compatible and fully specified at ±5V, 12V, and ±15V supply voltages.
