The recommended power-up sequence is to apply VCC first, followed by VEE. This ensures that the internal circuitry is properly biased and prevents unwanted current flows.
To ensure proper biasing, connect VEE to a negative voltage (typically -5V to -15V) and VCC to a positive voltage (typically +5V to +15V). This provides the necessary voltage swing for analog signals.
The DG403AK can operate up to 100 MHz, but the actual frequency limit depends on the specific application, PCB layout, and signal integrity. It's recommended to consult the datasheet and application notes for more information.
To minimize power consumption, ensure that the input signals are properly terminated, use a low-impedance power supply, and consider using a lower voltage supply (e.g., 3.3V instead of 5V) if possible.
To minimize signal degradation, use a symmetrical layout, keep signal traces short and away from noise sources, and use a solid ground plane to reduce electromagnetic interference (EMI).
