AD7890ARZ-2 Frequently Asked Questions (FAQs)

  • The AD7890ARZ-2 is a sensitive analog device, and proper layout and placement are crucial. It's recommended to keep the device away from high-frequency sources, use a solid ground plane, and keep analog and digital traces separate. Additionally, decoupling capacitors should be placed close to the device's power pins.
  • To ensure accurate conversion results, it's essential to use a single, stable voltage reference for the entire system. If multiple voltage references are unavoidable, ensure that they are all referenced to a common ground and that the AD7890ARZ-2 is configured to use the correct reference voltage.
  • To minimize distortion and ensure accurate conversions, it's recommended to use a low-impedance source to drive the analog input pins. A buffer amplifier or an op-amp can be used to drive the input pins, and the input signal should be filtered to remove high-frequency noise.
  • The AD7890ARZ-2 has internal overvoltage protection, but it's still important to protect the device from excessive voltage levels. Use external voltage limiting circuits or clamping diodes to prevent overvoltage conditions, and ensure that the input signal is within the specified range.
  • The AD7890ARZ-2 can be synchronized with an external clock or trigger signal using the CONVST pin. The CONVST pin should be driven by a low-jitter clock signal, and the device should be configured to use the external clock mode.
