The AD9834BRU is a 75 MHz low power direct digital synthesis (DDS) device from Analog Devices / Maxim Integrated. It produces high performance sine and triangular outputs, and includes an on-board comparator for square wave generation. The device operates from a 2.3V to 5.5V power supply and consumes only 20 mW at 3V, making it suitable for power-sensitive applications.
The DDS features a 28-bit tuning word width, providing fine frequency resolution. With a 75 MHz clock rate, resolution of 0.28 Hz can be achieved. The device supports frequency and phase modulation, controlled via a 3-wire SPI interface that operates at clock rates up to 40 MHz. The narrow-band SFDR is greater than 72 dB.
The AD9834BRU includes a power-down option via the SLEEP pin, allowing unused sections of the device to be powered down to minimize current consumption. The analog and digital sections are independent and can be powered from different supply voltages.
The device is available in a 20-lead TSSOP surface mount package and operates over an extended temperature range of -40°C to +105°C. It is suitable for frequency stimulus/waveform generation, frequency phase tuning and modulation, low power RF/communications systems, liquid and gas flow measurement, sensory applications, and test and medical equipment.
