Default Low distortion & noise digitally controlled volume chip

Found this today, looks interesting if it turns out to be real, it needs external opamps:

Indeed interesting. The audio specs are not much different from Crystal's CS3318 family, or TI's PGA family, but the uncommitted opamp is flexible, IF you need it...

The high signal levels are a pre for pro work, but useless for home hifi.

I thought so, even the data sheet illustrations looked familiar! The 8416 I think?

Edit: 8816. Still have the data sheet.

Found there's already a thread on this. I posted up the link because the datasheet had a very recent date on it - seems its not such a new part as that date suggests.

WM8816 based pre-amp

URL is death.
here the currently URL for the datasheet of DA6116 from Micro Analog Systems:
http://www.mas-oy.com/uploads/Data%20sheets/DA6116.pdf
and an additional thread to the same topic:
WTB: MAS DA6116 or MAS9116 or Wolfson WM8816

If anyone's interested in exploring alternative options for volume controls, these ADI chips are worth a look:

AD603 | Low Noise, 90 MHz Variable Gain Amplifier | Differential Amplifiers | Specialty Amplifiers | Analog Devices
AD605 | Dual, Low Noise, Single-Supply Variable Gain Amplifier | Differential Amplifiers | Specialty Amplifiers | Analog Devices

I've prototyped AD603 in the I/V stage of a DAC, sounds transparent to me. Still playing with AD605.
