Overview
The ADG714BRUZ-REEL, produced by Analog Devices Inc., is a complementary metal-oxide semiconductor (CMOS) octal single-pole, single-throw (SPST) switch. This device is controlled via a 3-wire serial interface compatible with serial peripheral interface (SPI), QSPI™, MICROWIRE™, and most digital signal processing (DSP) interface standards. The ADG714 is designed for low power consumption and operates over a supply range of 2.7 V to 5.5 V, making it suitable for a variety of applications. It is available in a 24-lead TSSOP package.
