ADGS1208/ADGS1209 Analog Multiplexers

Analog Devices’ iCMOS® serial peripheral interfaces (SPI) are ideal for communication, data acquisitions, and audio/video equipment

Image of Analog Devices ADGS1208/ADGS1209 Analog MultiplexersADI’s ADGS1208/ADGS1209 are analog multiplexers. The ADGS1208 comprises eight single channels and the ADGS1209 four differential channels. An SPI controls the switches and has robust error detection features, such as cyclic redundancy check (CRC) error detection, invalid read/write address detection, and SCLK count error detection. It is possible to daisy-chain multiple ADGS1208/ADGS1209 devices together. Daisy-chain mode enables the configuration of multiple devices with a minimal amount of digital lines.

The ADGS1208/ADGS1209 can also operate in burst mode to decrease the time between SPI commands. iCMOS construction ensures ultralow power dissipation, making the devices ideally suited 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 the supplies. In the off condition, signal levels up to the supplies are blocked. The ultralow on capacitance (CON) and exceptionally low charge injection (QINJ) of these multiplexers make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. ADGS1208/ADGS1209 are ideal analog multiplexers for communication, data acquisitions, and audio/video equipment.
