A good PCB layout for the DG202CSE-T involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. Additionally, it's recommended to use a low-ESR capacitor for the VCC pin and to minimize the length of the traces connected to the analog inputs.
The DG202CSE-T requires a single 2.7V to 5.5V power supply. It's recommended to power the device with a clean, low-noise power source. The power sequencing requirement is to power up the VCC pin before the logic inputs, and to power down the VCC pin after the logic inputs.
The maximum allowable voltage on the analog input pins is 5.5V. To protect the device from overvoltage, it's recommended to use voltage-limiting resistors or diodes in series with the analog inputs, and to ensure that the input voltage never exceeds the power supply voltage.
The DG202CSE-T can be configured for low-power operation by reducing the clock frequency, using the shutdown mode, or operating in the low-power mode. The trade-offs include reduced bandwidth, increased settling time, and decreased accuracy.
The recommended clock frequency range for the DG202CSE-T is 10 kHz to 1 MHz. The clock frequency affects the device's bandwidth, settling time, and accuracy. A higher clock frequency results in a wider bandwidth and faster settling time, but may also increase power consumption and noise sensitivity.
