Description

The ADGS1612 contains four independent single-pole/single-throw (SPST) switches. A serial peripheral interface (SPI) controls the switches. The SPI interface has robust error detection features, including cyclic redundancy check (CRC) error detection, invalid read/write address detection, and serial clock (SCLK) count error detection.It is possible to daisy-chain multiple ADGS1612 devices together. Daisy-chaining enables the configuration of multiple devices with a minimal amount of digital lines. The ADGS1612 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 ultralow on resistance (RON) of these switches make them ideal solutions for data acquisition and gain switching applications where low RONand low distortion are critical. The RONprofile is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals. The ADGS1612 exhibits break-before-make switching action for use in multiplexer applications. Note that throughout this data sheet, the multifunction pin,RESET/VL, is referred to either by the entire pin name or by a single function of the pin, for example, VL, when only that function is relevant.Product HighlightThe SPI interface removes the need for parallel conversion and logic traces and reduces general-purpose input/output (GPIO) channel count.Daisy-chain mode removes additional logic traces when multiple devices are used.CRC, invalid read/write address, and SCLK count error detection ensure a robust digital interface.CRC error detection capabilities allow the use of the ADGS1612 in safety critical systems.Guaranteed break-before-make switching allows the use of the ADGS1612 in multiplexer configurations with external wiring.Minimum distortion.ApplicationsCommunication systemsMedical systemsAudio and video signal routingAutomatic test equipmentData acquisition systemsBattery-powered systemsSample-and-hold systemsRelay replacements
