Overview
The ADGS5414BCPZ, produced by Analog Devices Inc., is a highly versatile and robust analog switch IC. This device features eight independent single-pole/single-throw (SPST) switches, each controlled via an SPI interface. The SPI interface includes robust error detection mechanisms such as cyclic redundancy check (CRC) error detection, invalid read/write address error detection, and SCLK count error detection. This makes the ADGS5414BCPZ suitable for a wide range of applications, including safety-critical systems. The device can operate in both single-supply and dual-supply configurations, with supply voltages ranging from 9 V to 40 V in single-supply mode and ±9 V to ±22 V in dual-supply mode.
