AD790AQ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper operation and prevents damage to the device.
  • To optimize the layout, keep the analog and digital grounds separate, use a solid ground plane, and minimize the distance between the AD790AQ and the analog input signal. Also, use a low-ESR capacitor for decoupling and place it close to the VCC pin.
  • The maximum input voltage that the AD790AQ can handle is 5.5V, which is the absolute maximum rating. However, the recommended input voltage range is from 0V to VREF (typically 2.5V or 5V).
  • Calibration involves adjusting the offset and gain of the AD790AQ to match the specific application requirements. This can be done using external resistors and capacitors, or through software calibration using a microcontroller or DSP.
  • The AD790AQ's performance is affected by temperature, with changes in offset voltage, gain, and linearity. The device is specified to operate from -40°C to 125°C, and the datasheet provides temperature-related specifications and graphs to help designers understand the effects of temperature on performance.
