Abstract
The present application discloses a low-voltage digital to analog conversion circuit, a data driving circuit and a display system. At least one voltage dividing unit comprises a number of resistors connected in series between a lower limit of voltage and an upper limit of voltage, and voltage dividing output terminals drawn from the resistors' connection nodes and an upper limit of voltage connection end. Introducing the voltage dividing unit renders the low-voltage digital signal to analog signal conversion circuit, the data driving circuit, and the display system low-voltage devices with low power consumption and small chip area.
