Non-modules have this feature.Module descriptionThe DAC902 is a high-speed, Digital-to-Analog Converter (DAC) offering a 12-bit resolution option .The DAC902 support updaterates in excess of 165MSPS with excellent dynamic performance,and are especially suited to fulfill the demands of a variety of applications.The advanced segmentation architecture of the DAC902 is optimized to provide a high Spurious-Free Dynamic Range (SFDR) for single-tone, as well as for multi-tone signals—essential when used for the transmit signal path of communication systems.The close matching of the current outputs ensures superior dynamic performance in the differential configuration.Its low power consumption allows for use in portable and batteryoperated systems. Further optimization can be realized by lowering the output current with the adjustable full-scale option.Generally, it can be used in digital microwave links, cable modems, arbitrary waveform generation, high-speed instrument control, video and digital TV.
Precautions for using the module(1) The module is a low power consumption module, and the power supply does not exceed 5.5V.(2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.(3) It is recommended to use the SMA corresponding interface for the output signal line. Mismatched interfaces are likely to cause poor contact, and poor quality wires may cause signal attenuation or excessive noise.(4) The delivered code is only used for the supporting main control board. No single-chip microcomputer tutorial is provided. Functions other than product details display need to be developed by yourself.(5) If you need to simply test the function of the module, it is recommended to use it with the control board of our store; after the correct wiring, the control board can be powered to achieve the analog voltage output.
Frequently asked questionsQ: What is the highest frequency that the DAC902 can generate a sine wave with the main control board of our store?A: The default output frequency of the main control board of our store is 1KHz. Since the single chip microcomputer cannot achieve the best performance of DAC902, there is no test limit value; generally, a high-speed processor such as FPGA is required to exert all its performance; the theoretical maximum is 33MHz Sine wave.Q: Can the output voltage range of the module be increased? What is the control accuracy? What should the output current capability be?A: At present, the circuit of the module can only output ± 1.25V, and the output voltage control accuracy is 1mV (low power ripple). The current output is within 50mA, and the magnification can be modified according to the schematic diagram to increase the output voltage, but the control accuracy will also decrease.Q: What is the difference between the clock on the SMA port on the board and the clock on the pin header?A: There is no difference. The SMA port has a better shielding effect and is more resistant to interference.
