The AD9830 is a numerically controlled oscillator using a phase accumulator, a sine look-up table and a 10-bit D/A converter integrated on a single CMOS chip.
The AD9830 integrates a numerically controlled oscillator, sine‑lookup table, phase accumulator and a 10‑bit DAC in a single 48‑pin QFP. It supports a 5 V power supply, up to 50 MHz clock rates, and provides both phase and frequency modulation capabilities.
Typical applications include direct‑digital‑synthesis (DDS) tuning, digital demodulation, and waveform generation. The device offers a low‑power sleep mode, a power‑down pin, and can drive loads up to 20 mA with a 1 V output compliance.
