Queries about ADL5902’s Response Time and Noise
Hi, thereI have some queries about the response time and noise of ADL5902 and need your help.From Figure 46 in the datasheet, assuming CLPF is 100nf, the noise is low and the rise time is about 100us,...

Re: AD623 Error in gain
Hello, I think the 1,6V input voltage describe the differential input voltage of the AD623, correct? What did you set as common mode voltage in your simulations? I think the output of the HCPL7840...

Hi Antonio, We apologize for the delay on your ADAU1452 issues. This is a feature of the ADAU1452 I am not as familiar with, and there is not much documentation on it's use at the present time. I...

Maybe you are right I didn't consider the common voltage in the simulation. I made a new simulation model this time with Vcom 2.5V. The amplifier works well until Vin 1.3 V differential and then...

Hi, Where I work we also prefer the simplicity of a plain double-sided PCB whenever possible. In one of our products we have "gotten away with" a double-sided board with a ADAU1701 (my post...

found it! it was the agilent 54622 scope injecting noise into the gound leads. not much but enough to trouble...when I turned the scope off it was clean..

Hi Jonathan: Yes, the errors occur randomly. And yes, 0V is from a source. I looked at the buffer amp outputs andthey are clean. Same results when the inputs are grounded. Tom

Hi Bhaskar, Can you give us more details regarding your hardware and software setup? Thanks,Dragos
View ArticleRe: AD623 Error in gain
The problem was on the common mode voltage. I measured it and it was 2.54 this make now sense and the results are similar with the simulations. Thanks very much.
