The ADGS5414 contains eight independent single-pole/single-throw (SPST) switches. An SPI interface controls the switches. The SPI interface has robust error detection features. These are CRC error detection, Invalid Read/Write Address detection and SCLK count error detection.
It is possible to daisy-chain multiple ADGS5414 devices together. This enables the configuration of multiple device with a minimal amount of digital lines. The ADGS5414 can also operate in burst mode to decrease the time between SPI commands.
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 very flat over the full analog input range, which ensures good linearity and low distortion when switching audio signals. The ADGS5414 exhibits break-before-make switching action allowing use of the device in multiplexer applications with external wiring.
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 and SCLK Count Error detection ensures a robust digital interface.
4. CRC and Error detection capabilities allows for the use of the ADGS5414 in safety critical systems.
5. Guaranteed Break-Before-Make switching allows external wiring of switches to deliver multiplexer configurations.
6. Trench isolation analog switch section guards against latch-up. A dielectric trench separates the P and N channel transistors thereby preventing latch
