has anyone uesd MAXQ3180 before?

hi,

Has anyone uesd MAXQ3180 before?
I have read its data sheet many times, esp. the first few pages, but I still can't find appropriate input voltage values for V0p,V1p,V2p and voltage differences btw I0p&I0N etc.
Pls help me out~~ thx

Looks like 0 to 2v based on page 3 data sheet. Section covering A to D.

 

[kusosan]

if you refer to the block diagram on page 5, there are some processes before V0p,V1p,V2p can be passed to ADC. So I think the voltage limits for them in front is different from the limits for ADC?

 

[Mikebits]

That is just a block diagram for ease of understanding. The spec on page 3 refers to the pin and that is what you should base on Pehaps you can breadboard to verify, if in doubt.

thanks Mikebits. I will try and see

Hi kusosan

Do you have results from your tests to this chip? Does it work as expected?

Best regards

Definitely the results are good

Hi

I am using this IC. I find the results at par, but the problem is still I have been working on the BETA versions of the IC. ie Rev A2.

Be careful.

Hello,

I am triyng to use this chip in my project.
As I understood, the working level of the ADC is 1Vpp. I did limit this levels to 70% for safe by hardware.
My problem is to run the MAXQ SPI communication with the MCU (an ATmega324P).
I didn't understand very well the stuff I found over internet (Google search).

I would appreciate so much any C code SPI routines for that.
