Product Details
The ADGS1412 contains four independent single-pole/single-throw (SPST) switches. 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 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
- SPI interface removes the need for parallel conversion, logic traces and reduces general-purpose input/output (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 ensures a robust digital interface.
- CRC and error detection capabilities allow the use of the ADGS1412 in safety critical systems.
- Guaranteed break-before-make switching allows the use of the ADGS1412 in multiplexer configurations with external wiring.
- Minimum distortion.
