GENERAL DESCRIPTION

The ADGS1208/ADGS1209 are analog multiplexers comprising

eight single channels and four differential channels, respectively. A

serial peripheral interface (SPI) controls the switches. The SPI

interface 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 (C

) and exceptionally low charge

injection (Q

INJ

) of these multiplexers make them ideal solutions

for data acquisition and sample-and-hold applications, where

low glitch and fast settling are required.

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

ADGS1208/ADGS1209 in safety critical systems.
