The ADGS1212 contains four independent single-pole/single-throw(SPST) switches. A serial peripheral interface (SPI)controls the switches. The SPI interface has robust error detectionfeatures such as cyclic redundancy check (CRC) error detection,invalid read/write address detection, and SCLK count errordetection.
It is possible to daisy-chain multiple ADGS1212 devices together.Daisy-chain mode enables the configuration of multiple deviceswith minimal digital lines. The ADGS1212 can also operate inburst mode to decrease the time between SPI commands.
iCMOS construction ensures ultralow power dissipation, makingthe device ideal for portable and battery-powered instruments.
Each switch conducts equally well in both directions when on,and each switch has an input signal range that extends to thesupplies.
In the off condition, signal levels up to the supplies are blocked.The ultralow capacitance and charge injection of these switchesmake them ideal solutions for data acquisition and sample-andholdapplications where low glitch and fast settling are required.
Fast switching speed coupled with high signal bandwidth makethe device suitable for video signal switching.
Multifunction pin names may be referenced by their relevantfunction only.
Product Highlights
- SPI interface removes the need for parallel conversion, logic traces, and reduces the general-purpose input/output (GPIO) channel count.
- Daisy-chain mode removes additional logic traces when multiple devices are used.
- CRC error detection, invalid read/write address detection, and SCLK count error detection ensure a robust digital interface.
- CRC and error detection capabilities allow the ADGS1212 to be used in safety critical systems.
- Guaranteed break-before-make switching allows the the ADGS1212 to be used in multiplexer configurations with external wiring.
- The ADGS1212 1.8 V logic compatibility with 2.7 V ≤ VL ≤ 3.3 V
- Ultralow capacitance.
- <1 pC charge injection.
