This is a complete low-cost stereo analog to digital converter for digital audio applications. The ADC comprises of a continuous time sigma delta modulator having a multibit quantizer and followed by a programmable OSR decimation filter.
The device is fabricated on TSMC 28HPC process
where high speed precision analog circuits are
combined with high density logic circuits.
