Module description:
The 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 eent dynamic performance,and are especially suited to fulfill the demands o variety opplications.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 , 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 ear power supply.
(3) It is recommended to use the SMA corresponding interface for the output signal e. 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.
