12-bit 1GS/s Dual Current Steering DAC
The S3DAIQ1G12BT16FFC 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.
This 12-bit Dual DAC features an excellent static performance that includes ±0.8LSB DNL and ±2.0LSB INL for typical
conditions.
Dynamic performance highlights considering a signal frequency of 54MHz and 1GS/s conversion rate include an SNR
> 68dB and an SFDR > 65dBc.
The S3DAIQ1G12BT16FFC is designed in a 16nm logic process, which is ideal for integration with a DSP engine, and
can be cost-effectively ported across foundries and process nodes upon request.
