Re: ADP5090 EVB question
Hi Kun-jing, May I know the resistor value you put after the power supply? It will limit the input power to ADP5090. The input current should be (1.5-0.75)/R.If this current can support the output...

Re: EV-AD5415 EVB was not able to output 35V, any suggestion
Hi Kevin, The addition of gain will have an impact on the noise of the circuit. To minimize the gain noise, a low noise op-amp should be connected to the AD5415 output. Please, find the documentation...

Hello... Page 18 of the data sheet says to tie FB_CLK_N to GND if in CMOS mode, while page 91 of the reference manual (UG-570) says to leave FB_CLK_N unconnected in CMOS mode... which is it? Thanks,John
View ArticleRe: AD9361 Feedback clock termination
It will work either way. Some designers prefer to have all the pins terminated and tie it to GND and if your preference is to leave it open you can do that too.
