The ADGS1408/ADGS1409 are analog multiplexers comprisingeight single channels and four differential channels, respectively.A serial peripheral interface (SPI) controls the switches. The SPIinterface has robust error detection features such as cyclicredundancy check (CRC) error detection, invalid read/writeaddress detection, and SCLK count error detection.
It is possible to daisy-chain multiple ADGS1408/ADGS1409devices together. Daisy-chain mode enables the configuration ofmultiple devices with a minimal amount of digital lines. TheADGS1408/ADGS1409 can also operate in burst mode todecrease the time between SPI commands.
iCMOS construction ensures ultra low power dissipation, makingthe devices ideally suited for portable and battery-poweredinstruments.
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 suppliesare blocked.
The on-resistance profile is flat over the full analog input range,which ensures linearity and low distortion when switchingaudio signals.
Product Highlights
- SPI interface removes the need for parallel conversion, logic traces, and reduces 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 use of the ADGS1408/ADGS1409 in safety critical systems.
- Minimal distortion.
