24-bit Sigma Delta Stereo Audio DAC in TSMC 28nm

DA24SD28HPC is a complete low-cost stereo digital to analog converter for audio applications. The DAC comprises of digital interpolating filters, a third order single loop multibitbit sigmadelta DAC, followed by a continuous time reconstruction filter. It has a single ended analog output. The device is fabricated on TSMC 28HPC process where high speed precision analog circuits are combined with high density logic circuits.
