AD7899ARS-2 Frequently Asked Questions (FAQ)
-
A good layout and routing practice is to keep the analog and digital grounds separate, use a star-ground configuration, and keep the analog signal traces away from the digital signal traces. Additionally, use a solid ground plane and avoid vias under the device to minimize noise and radiation.
-
The self-test feature can be enabled by setting the ST pin high. This feature checks the internal circuitry and analog-to-digital conversion process. If not used, the device will still function normally, but it may not detect internal faults or errors. It is recommended to use the self-test feature to ensure the device is functioning correctly, especially in critical applications.
-
The maximum clock frequency for the AD7899ARS-2 is 1.5 MHz. Exceeding this frequency may result in incorrect conversions, increased noise, and reduced accuracy. It is recommended to use a clock frequency below the maximum specified to ensure reliable operation.
-
The POR and BOR features ensure that the device resets to a known state during power-up or brown-out conditions. The POR is initiated when the supply voltage rises above 1.5 V, and the BOR is initiated when the supply voltage falls below 1.4 V. The device will automatically reset and restart conversions when the supply voltage returns to a stable state.
-
It is recommended to use a 10 μF ceramic capacitor and a 1 μF film capacitor in parallel, placed close to the device's power pins, to decouple the power supply. Additionally, a ferrite bead or a small inductor can be used to filter out high-frequency noise.
