| description | The present disclosure provides a digital to analog conversion (DAC) circuit and a data source circuit chip, the DAC circuit includes: first MOS tubes with the same number of the inputted digital bits; a second resistance, one end of the second resistance connects to the reference voltage, another end of the second resistance connects to the output terminal of the circuit; a second MOS tube, the drain of the second MOS tube connects to the output terminal of the circuit, the gate of the second MOS tube receives a row blank signal; and a capacitor, one end of the capacitor connects to the output terminal, another end of the capacitor is grounded. Using the above circuit and data source circuit chip, can greatly reduce the number of the MOS tube used in the DAC circuit, to effectively reduce the volume of the data source circuit chip and cost. |
