AD7821KN 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 and prevents any potential latch-up conditions.

  • To ensure accurate conversions, it is essential to provide a clean and stable analog input signal, ensure proper grounding and shielding, and use a suitable reference voltage. Additionally, the analog input signal should be within the specified range, and the conversion clock should be stable and within the recommended frequency range.

  • The SYNC pin is used to synchronize the conversion process with an external clock or signal. When the SYNC pin is low, the AD7821KN enters a low-power state, and when it is high, the conversion process is initiated. This pin can be used to synchronize multiple AD7821KN devices or to interface with other devices that require a synchronized conversion process.

  • Yes, the AD7821KN can be used with a single 5V power supply. The device has an internal voltage regulator that generates the required internal voltages from the 5V supply. However, it is essential to ensure that the 5V supply is clean and stable to prevent any potential issues with the conversion process.

  • The maximum throughput rate of the AD7821KN is 100 kSPS (kilo-samples per second). This means that the device can perform up to 100,000 conversions per second, making it suitable for high-speed data acquisition applications.
