AD9912 datasheet



The AD9912 is a direct digital synthesizer (DDS) that features an integrated 14-bit digital-to-analog converter (DAC). The device features a 48-bit frequency tuning word (FTW) that can synthesize frequencies in step sizes no larger than 4 μHz. Absolute frequency accuracy can be achieved by adjusting the DAC system clock.


1. 1 GSPS internal clock speed (up to 400 MHz output directly)

2. Integrated 1 GSPS 14-bit DAC

3. 48-bit frequency tuning word with 4 μHz resolution

4. Differential HSTL comparator
