ADGS5412BCPZ-RL7

The ADGS5412 contains four independent single-pole/singlethrow (SPST) switches. A serial peripheral interface (SPI) controls the switches. The SPI interface has robust error detection features, including cyclic redundancy check (CRC) error detection, invalid read/write address detection, and serial clock (SCLK) count error detection. It is possible to daisy-chain multiple ADGS5412 devices together, which enables the configuration of multiple devices with a minimal amount of digital lines. The ADGS5412 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 ADGS5412 exhibits break-beforemake switching action, allowing use of the device in multiplexer applications with external wiring.
