Overview
The ADG715BRUZ-REEL7, produced by Analog Devices Inc., is a CMOS, low-voltage, serially controlled, octal SPST (single-pole, single-throw) switch. This device is designed to operate with a 2-wire serial interface compatible with the I2C interface standard. It features four hardwired addresses selectable from two external address pins (A0 and A1), allowing up to four devices to be connected to the bus. The ADG715 is ideal for applications requiring low power consumption and fast switching times, with an operating supply range of 2.7 V to 5.5 V and the option for a dual ±2.5 V supply.
