Midas M9000 120 dB Stereo D/A Converter (TSSOP-28)

The M9000 is a complete stereo 24 bit/192 kHz digital to-analog system. This D/A system includes digital deemphasis, half dB step size volume control, ATAPI channel mixing, selectable fast and slow digital interpolation filters followed by an oversampled multi-bit delta-sigma modulator that includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Following this stage is a multi-element switched capacitor stage and low pass filter with differential analog outputs.

The M9000 also has a proprietary DSD processor that allows for volume control and 50 kHz on-chip filtering without an intermediate decimation stage. It also offers an optional path for direct DSD conversion by directly using the multi-element switched capacitor array.
