Overview
The ADG714BRU, produced by Analog Devices Inc., is a complementary metal-oxide semiconductor (CMOS) octal single-pole, single-throw (SPST) switch. It is controlled via a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and most digital signal processing (DSP) interface standards. This device is characterized by its low on-resistance, flat over the full signal range, and low power consumption. The ADG714BRU operates on a single supply voltage ranging from 2.7 V to 5.5 V and can also be supplied from a dual ±2.5 V supply. It is available in 24-lead TSSOP and 24-lead LFCSP packages, making it versatile for various applications.
