I'm building a board with a DSP. The DSP does a FFT on a analog signal. The signal is given a offset and we amplified with a ADA4853-1.
Then the Signal goes to the AD8324.
The AD8324 is set in single-ended. The Signal goes to the ADC on the DSP.
With an Logic Analyzer I have seen the SPI bus.
Clk: 1 MHz
Sleep (inverted): High
Data (inverted): Low
Clk: 0 Hz
Data (inverted): High
And the AD8324 is still not amplifying. Picture : Channel 1: Input... Channel 2: Output
I don't know what's wrong!
Can you share with us the schematic of AD8324?
Okay i found my mistake! Because it is an evolution of the board, I forgot to look at the output side! I forgot the balun transformers! ... Thanks Anna
after fixing my Board and my schematic, the problem still exist. I don't know what's wrong
i need you help, please!
Thank you very much!
I think you may have misunderstood the function of the TXEN pin. It is for signal tranmission through the part not data transmission to the register. The TXEN pin must be HIGH to enable forward signal transmission.
