AD7858LARSZ Frequently Asked Questions (FAQs)

  • A good layout and routing practice is to keep the analog and digital signals separate, use a solid ground plane, and keep the sensitive analog signals away from the digital signals. Also, use short and direct traces for the analog signals, and avoid crossing digital signals over the analog signals.
  • The AD7858LARSZ has an internal calibration circuit that can be used to calibrate the device. However, for optimal performance, it is recommended to perform an external calibration using a known reference voltage and a calibration routine that takes into account the specific application requirements.
  • The maximum sampling rate of the AD7858LARSZ is 200 kSPS. However, the actual sampling rate that can be achieved depends on the clock frequency, the conversion mode, and the interface mode. The device also has a limitation on the minimum conversion time, which can affect the maximum sampling rate.
  • Common error sources include incorrect clock frequency, incorrect voltage supply, incorrect pin connections, and noise on the analog input signals. To troubleshoot, check the device's status register, verify the clock frequency and voltage supply, and ensure that the analog input signals are within the specified range.
  • Yes, the AD7858LARSZ can be used in a multi-channel application. To configure it, use the device's channel select pins to select the desired channel, and use the device's sequencer mode to sequence through the channels. The device can also be used in a pseudo-differential mode to reduce the number of pins required for multi-channel applications.
