    摘要: The present invention discloses a method for enhancing the driving capability of a digital to analog converter, wherein a voltage higher/lower than the intended output voltage is used to pre-charge/pre-discharge the capacitor of the output load; when the capacitor is charged/discharged to near the intended output voltage, the operation is switched back to the normal mode; and the pre-charge operation may adopt the fixed charge voltage-varying charge time mode or the fixed charge time-varying charge voltage mode.
