The AD9832-KGD is a numerically controlled oscillator employing a phase accumulator, a sine look-up table, and a 10-bit digital-to-analog converter (DAC) integrated on a single CMOS chip. Modulation capabilities are provided for phase modulation and frequency modulation.

Clock rates up to 25 MHz are supported. Frequency accuracy can be controlled to one part in 4 billion. Modulation is effected by loading registers through the serial interface.

A power-down bit lets the user power down the AD9832-KGD when it is not in use, the power consumption being reduced to 5 mW (5 V) or 3 mW (3 V).
