Overview
The ADG1414BCPZ-REEL7, produced by Analog Devices Inc., is a monolithic complementary metal-oxide semiconductor (CMOS) device. It features eight independently selectable single-pole, single-throw (SPST) switches designed on an industrial CMOS (iCMOS®) process. This process combines high voltage CMOS and bipolar technologies, enabling the switches to tolerate high supply voltages while providing increased performance, lower power consumption, and reduced package size. The device is controlled via a versatile 3-wire serial interface compatible with standard SPI, QSPI™, MICROWIRE™, and DSP interface standards, operating at clock rates up to 50 MHz.
