Waveform Generator
AD9832 Data Sheet
FEATURES GENERAL DESCRIPTION 25 MHz speed
On-chip SIN lookup table
On-chip, 10-bit DAC
Serial loading
Power-down option
Temperature range: −40°C to +85°C
200 mW power consumption
16-Lead TSSOP The AD9832 is a numerically controlled oscillator employing
a phase accumulator, a sine look-up table, and a 10-bit digitalto-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 allows the user to power down the AD9832
when it is not in use, the power consumption being reduced to
5 mW (5 V) or 3 mW (3 V). The part is available in a 16-lead
TSSOP package. APPLICATIONS
