Abstract
A low-power data conversion system for converting a serial digital data input signal (DIN) to an analog output signal (Vout) by generating the serial digital data input signal (DIN) at a first sample rate (fsin) in a burst mode, wherein the sampling frequency of the serial digital data input signal (DIN) has a predetermined ratio to the frequency of an external reference clock signal (SLEEPCLK or WCLK). The serial digital data input signal (DIN) is converted into parallel format. A FIFO system temporarily stores a predetermined number of samples (Din) of the parallel format digital data input signal. The samples (Din) have a first sample rate (fsin). The samples (Din) are converted to an analog output signal (Vout).
