The ADGS5414 contains eight independent single-pole/single-throw (SPST) switches. An 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 ADGS5414 devices together. This enables the configuration of multiple devices with a minimal amount of digital lines. The ADGS5414 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.Product HighlightsThe SPI interface removes the need for parallel conversion, logic traces, and reduces the general-purpose input/output (GPIO) channel count.Daisy-chain mode removes the need for additional logic traces when using multiple devices.CRC error detection, invalid read/write address error detenction, and SCLK count error detection ensures a robust digital interface.CRC and error detection capabilities allow the use of the ADGS5414 in safety critical systems.Break-before-make switching allows external wiring of the switches to deliver multiplexer configurations.The trench isolation analog switch section guards against latch-up. A dielectric trench separates the positive and negative channel transistors, preventing latch-up even under severe overvoltage conditions.ApplicationsRelay replacementAutomatic test equipmentData acquisitionInstrumentationAvionicsAudio and video switchingCommunication systems
