FAQ's
  • Does the increase in the number of bits for A/D conversion cause a change of sampling time?
    • When the number of bits is increased (resolution is increased), high accuracy is required for the voltage charged in the sample/hold circuit accordingly. This causes the sample/hold circuit charging time to increase, and therefore the sampling time needs to be increased.
      For the calculation method of sampling time, visit the support site and refer to the following document.
