The AD9913 Rev. A is a low power 250 MSPS 10-bit DAC 1.8 V CMOS Direct Digital Synthesizer.
The AD9913 Direct Digital Synthesizer (DDS) is designed for portable, handheld and battery‑powered equipment. It integrates a 10‑bit DAC, a 100 MHz analog output, and supports up to 250 MSPS internal clock speed while consuming as little as 50 mW. The device offers programmable frequency, phase, and linear sweep modes, as well as optional PLL multiplication and internal oscillator options.
The datasheet provides detailed electrical specifications, pin configurations, timing characteristics, and typical performance graphs. It also includes a functional block diagram, register maps, and an ordering guide for the 32‑lead LFCSP package.
