AD9833BRMZ

数据采集ADC/DAC –  Low Power, 12.65 mW, 2.3 V to 5.5 V,  Programmable Waveform Generator

GENERAL DESCRIPTION AD9833BRMZ

The AD9833 is a low power, programmable waveform generator capable of producing sine, triangular, and square wave outputs. Waveform generation is required in various types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable, allowing easy tuning. No external components are needed. The frequency registers are 28 bits wide: with a 25 MHz clock rate, resolution of 0.1 Hz can be achieved; with a 1 MHz clock rate, the AD9833 can be tuned to 0.004 Hz resolution.
