ADS7850IRTER Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD (analog supply) first, followed by VCC (digital supply), and then the clock signal. This ensures proper initialization of the device.
  • To optimize the analog input impedance, use a low-impedance source (e.g., an op-amp buffer) and keep the input traces short and well-shielded. This minimizes signal attenuation and noise pickup.
  • The maximum clock frequency for the ADS7850 is 20 MHz. Exceeding this frequency may result in incorrect conversions or device malfunction.
  • The BUSY signal indicates when the ADC is busy with a conversion. Wait for the BUSY signal to go low before initiating a new conversion or accessing the conversion result.
  • The REFSEL pin selects the internal reference voltage (VREF) or an external reference voltage. Tie REFSEL high to use the internal VREF or low to use an external reference voltage connected to the VREF pin.
