Overview
The ADG1414BRUZ-REEL7, manufactured 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 using the industrial CMOS (iCMOS) process. This process combines high voltage CMOS and bipolar technologies, allowing the device 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 that operates at clock rates of up to 50 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards. Each switch conducts equally well in both directions, and the input signal range extends to the supplies.
