some question about DAC

Dear all,

I am now doing a research on RFID (ISO15693) system. But I am not understand how the signal being process.

Example, I have a DSP giving out 8 bits data in parallel with data transfer rate 26.48KHz to a Digital Analog Converter (DAC). What will the output signal that I have at my DAC otuput? Will it a sinusoidal signal with 423KHz?

Where can I get more information in this topic?


Thanks
 

Re: some question about DAC

Hi tok47,

I am not sure about that. The DAC receives 8 bit digital word that converts to analog signal. If the rate of changing the word is 26KHz, the sinosoid on the output should be maximum 26KHz/3 !!

Try some DAC producers. Analog Devices, Maxim...

Regards,
