ADI’s ADGS5414 contains eight independent single-pole/single-throw (SPST) switches. A serial peripheral interface (SPI) interface controls the switches and has robust error detection features, including cyclic redundancy check (CRC) error detection, invalid read/write address error detection, and SCLK count error detection. It is possible to daisy-chain multiple devices together. This enables the configuration of multiple ADGS5414 with a minimal amount of digital lines. The device can also operate in burst mode to decrease the time between SPI commands.

Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The on-resistance profile is flat over the full analog input range, ensuring ideal linearity and low distortion when switching audio signals. The ADGS5414 exhibits break-before-make switching action, allowing the use of the device in multiplexer applications with external wiring. The ADGS5414 is ideal for communication systems, avionics, and test/measurement applications.
