12-Bit 325MS/s Dual Current Steering DAC - SMIC 55nm LL
The S3DAIQ325M12BSM55LL 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.
This 12-bit Dual DAC features an excellent static performance that includes ±0.5LSB DNL and ±1.0LSB INL for typical conditions.
Dynamic performance highlights considering a signal frequency of 10MHz and 325MS/s conversion rate include an SNR= 68dB and an SFDR=70dBc.
