This provides the perfect cost effective solution when connecting the digital audio output from a TV display to an analog. The XT-DAC-12 also includes a digital converter which converts optical audio into a coaxial digital output. Elimination of the cascode reduces transistor headroom requirements and allows the DAC to be built with a 1.8V supply. The XT-DAC-12 is designed to convert either coaxial or optical signals from a digital signal to analog stereo audio. Smaller current source transistors have a lower drain capacitance, allowing large high frequency output impedance to be achieved without an extra cascode transistor. A sigma-delta architecture allows the current source transistors to be smaller since mismatch shaping is employed.
A narrow-band sigma-delta DAC with eight unit elements is chosen to demonstrate the radio frequency digital-to-analog converter (RF DAC) concept. An image of a low IF input signal can therefore be output directly at a high IF or RF frequency for transmit communications applications. The architecture has the additional benefit of mixing the DAC impulse response energy to a higher frequency.

The waveforms can be aligned so that the data switching occurs in the zero regions of the oscillating output. The oscillating waveform should be a multiple (k*fs) of the sampling frequency (f), where k>l. A DAC output current controlled by an oscillating waveform is proposed to mitigate the effects of the switching distortion. Inter-symbol interference (ISI), imperfect timing synchronization and clock jitter are all culprits. It takes audio from your multichannel S/PDIF or TOSLINK digital audio source and converts it to standard L/R analogue audio, available for connection to an external device such as an amplifier or recording deck via standard RCA-Style jacks.
