Description

The AD9834BRU is a 75 MHz low power DDS device capable of producing high performance sine and triangular outputs. It also has an on-board comparator that allows a square wave to be produced for clock generation. Consuming only 20 mW of power at 3 V makes the AD9834 an ideal candidate for power-sensitive applications.Capability for phase modulation and frequency modulation is provided. The frequency registers are 28 bits; with a 75 MHz clock rate, resolution of 0.28 Hz can beachieved. Similarly, with a 1 MHz clock rate, the AD9834 can be tuned to 0.004 Hz resolution. Frequency and phase modulation are affected by loading registers through the serial interface and toggling the registers using software or the FSELECT pin and PSELECT pin, respectively. AD9834BRU Features • Narrow-band SFDR >72 dB • 2.3 V to 5.5 V power supply • Output frequency up to 37.5 MHz • Sine output/triangular output • On-board comparator • 3-wire SPI® interface • Extended temperature range: -40°C to +105°C • Power-down option • 20 mW power consumption at 3 V • 20-lead TSSOP AD9834BRU Applications • Frequency stimulus/waveform generation • Frequency phase tuning and modulation • Low power RF/communications systems • Liquid and gas flow measurement • Sensory applications: proximity, motion, and defect detection • Test and medical equipment
