analog signal delay

Dear,

的re are several delay components in SLG46517M chip as I know, and I want to give few micro seconds of delay to analog signal.

I set the pin as Analog input/output and made a delay component by using "combination function components",

then I found that it's not allowed to connect the wire from "analog input/output' to "delay component".

It seems it's not possible to make delayed analog signal, is it right? Or if possible, could you give me any advice?

One more question, is it possible to implement analog voltage divider by GreenPAK? Just simple divider (e.g., input voltage of 3V, divide it to 1V and 2V)

I think GreenPAK is very useful to implement digital circuits, but it seems hard to implement analog circuits.

Thanks.

Dear Yuseungho,

Dear Yuseungho,

的analog input can be connected only to ACMP block, which has a digital output. There are two dedicated analog inputs (PIN6 and PIN12), which are also hardware connected to P-FETs. If you know the analog voltage level you can apply this voltage to analog PIN connected to ACMP and P-FET input. After the voltage increases more than the ACMP threshold you can use the output of ACMP, delay it on some time, and than apply ON signal to the P-FET input. Please see the attachment. I hope it will help you

的oretically yes, but it is not common GPAK usage. All the PINs have Pull-Up or Pull-Down resistors. You can configure one PIN as input with Pull up resistors, the second PIN with Pull down resistor (I recommend to use analog inputs), connect them externally, as a result, you will get voltage divider.

Best regards,
