AD7820TQ Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly.
-
To optimize the layout, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog and digital signal traces separate. Also, place the AD7820TQ close to the analog signal sources and use short, direct connections.
-
The maximum clock frequency that can be used with the AD7820TQ is 20 MHz. However, the actual clock frequency used may be limited by the specific application and the required conversion rate.
-
The BUSY signal is an open-drain output that goes low when the AD7820TQ is busy with a conversion. To use this signal, connect it to a pull-up resistor and a logic input. The BUSY signal can be used to synchronize the conversion process with other system components.
-
A 0.1 μF ceramic capacitor should be placed between VCC and GND, and a 10 μF capacitor should be placed between AVCC and GND. These capacitors help to filter out noise and ensure stable operation.
