GENERAL DESCRIPTION
The ADGS1408/ADGS1409 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 ADGS1408/ADGS1409
devices together. Daisy-chain mode enables the configuration of
multiple devices with a minimal amount of digital lines. The
ADGS1408/ADGS1409 can also operate in burst mode to
decrease the time between SPI commands.
iCMOS construction ensures ultra low 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
Rev. 0

supplies. In the off condition, signal levels up to the supplies
are blocked.
The on-resistance profile is flat over the full analog input range,
which ensures linearity and low distortion when switching
audio signals.
PRODUCT HIGHLIGHTS
1. SPI interface removes the need for parallel conversion,
logic traces, and reduces GPIO channel count.
2. Daisy-chain mode removes additional logic traces when
multiple devices are used.
3. CRC error detection, invalid read/write address detection,
and SCLK count error detection ensure a robust digital
interface.
4. CRC and error detection capabilities allow the use of the
ADGS1408/ADGS1409 in safety critical systems.
5. Minimal distortion.
