Digital/analog converting driver and method

A digital/analog converting method comprising:

• inputting digital data having M+N bits to a digital/analog converting driver;
• dividing the digital data by the M bits and the N bits;
• converting the M bits and the N bits into corresponding voltages;
• wherein the M bits are converted by a capacitor using charging and dividing operations of capacitors and the N bits are converted by a resistor string;
• adding the voltages;
• and
• outputting the added voltage as an analog voltage.

A digital/analog converting driver that converts digital data having M+N bits, where M and N are integers, into an analog voltage, comprising:

• a first converting unit that converts M bits of the digital data into a first voltage;
• a second converting unit that converts N bits of the digital data into a second voltage;
• and
• a sample-and-hold unit which samples the second voltage in a sample mode, and outputs the analog voltage by adding the first voltage and the second voltage in a hold mode.
