GENERAL DESCRIPTION
The ADGS1412 contains four independent single-pole/single-
throw (SPST) switches. An 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 ADGS1412 devices together.
Daisy-chain mode enables the configuration of multiple devices
with a minimal amount of digital lines. The ADGS1412 can also
operate in burst mode to decrease the time between SPI
commands.
iCMOS construction ensures ultralow power dissipation, making
the device 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 on-resistance profile is flat over the full analog input range,
which ensures good 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 ensures a robust digital
interface.
4. Safety integrity level (SIL)-compatible.
5. Minimum distortion.
