The recommended power-up sequence is to apply VCC first, followed by VEE, and then the digital inputs. This ensures proper device operation and prevents latch-up.
During power-down, it is recommended to disconnect the analog signals from the switches to prevent backfeeding of the analog signals into the power-down circuitry.
The maximum voltage that can be applied to the analog switches is ±30V, but it is recommended to limit the voltage to ±20V to ensure reliable operation and prevent switch degradation.
To minimize the effect of charge injection, it is recommended to use a low-impedance source, keep the analog signal paths as short as possible, and use a shielded cable to connect the analog signals to the DG508ABK.
The recommended layout and routing for the DG508ABK involves keeping the analog signal paths separate from the digital signal paths, using a solid ground plane, and minimizing the length of the analog signal paths.
