CMOS
The MC145073 is a dual–channel, 16–bit A/D converter intended for use in digital audio systems such as multimedia, DCC, DAT, and professional audio applications.
It uses a sigma–delta architecture consisting of a second–order analog modulator and two stages of digital filtering for each channel.
The analog modulator samples the input signal at 128 times the output data rate, performs a single–bit quantization, and shapes the quantization noise towards higher frequencies.
Subsequent on–chip digital filters reject most of the shaped quantization noise and lowe...
