Overview
The ADG752BRMZ-REEL7, produced by Analog Devices Inc., is a low voltage SPDT (single pole, double throw) switch. It is designed using a T-switch configuration, which provides excellent off-isolation and maintains good frequency response in the on condition. This switch is suitable for switching RF and video signals due to its high off-isolation and wide signal bandwidth. It operates within a supply range of +1.8 V to +5.5 V, making it ideal for battery-powered and portable instruments. The ADG752 is built on a submicron process, ensuring low power dissipation, high switching speed, and low on-resistance. It is a fully bidirectional switch and features break-before-make switching action to protect input signals from momentary shorting during channel switching.
