Re: ADL5511 Evaluation board
Ok, thanks for doing that. A few observations that might explain what you are seeing. At lower frequencies, it the ADL5511 Venv output clips when Pin is about +15 dBm. In your measurements, it...

Hi, The legacy AD6654 evaluation board did not support continuous streaming of data due to limitations of the onboard memory buffers and the USB PC interface. Best Regards,Tony M
View ArticleRe: ADAU1442 + AD1938 ADC Noise
Ok!! So I found that the problem was that CLATCH of the CODEC was asserted when it shouldn't, So when SPI was operating (reading DSP), it was going crazy. Now I have a different problem: When reading...

Click noise reading data from DSP
Hello, how are you? I am working on a test equipment with ADAU1442 + AD1939. Everything works good, except that when I perform any reading operation, the DSP clicks and pops. SPI is running at 500Khz....
View ArticleRe: ADP5090 EVB question
Hi, Firstly, you need to mak sure the input power bigger than output power considering the efficiency. (Pin=Vin*Vin/4/R)Secondly, there is a OCV detecting time around 300ms when the ADP5090 can't...
