Re: ADC AD9625 evaluation board Power supply
Hi Soumya- 1) The evaluation board for AD9625 does have support for 3.3V on DVDD_IO & SPI_DVDD_IO. The datasheet for AD9625 will only specify 2.4 to 2.6V for these domains. The 3.3V support may...

Ultimately, we hope to interface the ADIS to a single board computer. The aim is to use the ADIS data to perform real-time sensor motion compensation. A good first step is to use the EVAL board to...

Re: ADG9xx RF level
Hi Michele, When the part is handling an RF signal then the ADG9xx can handle a 7dBm (0.7Vp) signal and with a 0.5V DC bias it can pass a 16dBm (2Vp) signal. This is determined by the lower limit in...
