Overview
The ADG752BRMZ is a low voltage, single pole, double throw (SPDT) analog switch designed by Analog Devices Inc. This device is constructed using a T-switch configuration, which provides excellent off-isolation and maintains good frequency response in the on condition. It is ideal for switching RF and video signals due to its high off-isolation and wide signal bandwidth. The ADG752BRMZ operates on a single supply voltage ranging from 1.8 V to 5.5 V, making it suitable for battery-powered and portable instruments. The switch is fully bidirectional and can handle signals up to and including the supply rails, with a break-before-make switching action to protect against momentary shorting between channels.
