The ADGS5412BCPZ-RL7 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, including cyclic redundancy check (CRC) error detection, invalidread/write address detection, and serial clock (SCLK) counterror detection.
It is possible to daisy-chain multiple ADGS5412BCPZ-RL7 devices together,which enables the configuration of multiple devices with aminimal amount of digital lines. The ADGS5412BCPZ-RL7 can also operate in burst mode to decrease the time between SPIcommands.
Each switch conducts equally well in both directions when on,and each switch has an input signal range that extends to thesupplies. 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 ADGS5412BCPZ-RL7 exhibits break-before-make switching action, allowing use of the device in multiplexer applications with external wiring.
Product Highlights
Trench isolation analog switch section guards against latch-up. A dielectric trench separates the positive (P) and negative (N) channel transistors thereby preventing latch-up even under severe overvoltage conditions.
