SV: Re: [sdiy] 16bit DC, DAC, SPI!

[Bruce Duncan]

The LTC1655 looks pretty nice. I've also got an application that uses 
the LTC26x4 quad SPI DAC. They're around $5-$10 (non-stock @ Digi-Key 
however) depending on resolution (12, 14, or 16). Small package, but 
the SPI clock rate is 50MHz so you can use them for fast sample 
rates. Plus the DNL is better than 0.2LSB on the 16-bit part!

Isn't it the accuracy or Integral Nonlinearity in LTC speak that is 
the more important spec for DC.
In the LTC1655 case it is +/-8 LSB same as the AD5663
