Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Type: Module _x005f_x000D_ Condition: New _x005f_x000D_ Supply Voltage: 2.3 to 5.5 V _x005f_x000D_ Model Number: DDS Signal Generator _x005f_x000D_ 1.The AD9833 is a low-power, programmable sine waveform generator required for generating waveforms in all types of waveform detection, realisation, and time domain reflectometer (TDR) applications. _x005f_x000D_ 2. The output frequency and phase are software programmable and can be easily adjusted. No external components are required. The frequency register is 28 bits wide: clocked at 25 MHz for 0.1 Hz resolution; the AD9833 is clocked at 1 MHz with resolution tunable to 0.004 Hz. _x005f_x000D_ 3. Write through the serial interface line. The serial interface operates at clock frequencies up to 40 MHz and is compatible with DSP and microcontroller standards. The device is powered by a 2.3V 5.5V supply.  _x005f_x000D_ 4. Has a power-down function (SLEEP). This allows unused parts of the device to be switched off, thus minimising the power consumption, for example, switching off the DAC when generating the output clock. _x005f_x000D_ 5. The standard serial interface allows the device to be connected directly to different microprocessors. The device uses an external serial clock to write data or information to the control device. _x005f_x000D_ 3-wire SPI interface  _x005f_x000D_ Extended temperature range: -40°C to + 105°C  _x005f_x000D_ Power-down options :                                                           _x005f_x000D_ Update rate: 25 (large)  _x005f_x000D_ VOUT large: 0.65 V Small VOUT: 38 mV  _x005f_x000D_ VOUT temperature coefficient: 200°  _x005f_x000D_ Input high voltage: 1.7-2.8V Input low voltage: 0.5-0.7V  _x005f_x000D_ Input Current: 10uA  _x005f_x000D_ Input capacitance: 3pF  _x005f_x000D_ Operating temperature range: -40°C to +105°C, typical specification 25°C  _x005f_x000D_ Size: 17x12x3mm/0.67x0.47x0.12inch _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
