The S3DAIQ20M12BSM55LL employs a current steering architecture with differential current outputs. It uses 6 linear bits and 6 binary bits, all of which are generated from within the current source array.
This segmentation results in an excellent static performance and reduced glitch energy at the output. This also ensures parasitics within the DAC are minimized. Furthermore, the distortion at the output is greatly reduced by using propriety latch architecture and randomization of the output current sources.
The combination of static performance, reduced glitch energy, minimized parasitics and reduced distortion, results in outstanding dynamic performance over a wide range of conditions including frequencies close to the DAC Nyquist frequency.
