RE: Reg QADC

Hello Vijay,

  I don't know much about MPC565. But MPC561 series (i.e., Silver Oak/
Green Oak) offers this selection. It is possible to configure individual
ADC channels to process at different analog input voltages called VREF
and ALTREF.

Best Regards,
Manoj.

Subject: [MPC500] Reg QADC

Hello 
     I have a question regarding the QADC in MPC565. We were 
considering using the processor for a new project. But found that in 
other processors (say from Infineon) you can configure the range of 
analog input value. So instead of the standard 0-5V it is possible to 
configure it as 0-100mv so that there is minimal loss of resolution. 
Our application demands programmable ADC ranges that is from 0-100mv, 1-
1.5V etc. Is it possible to configure individual ADC channels to 
process at different analog input voltage ranges in the MPC565?

Regards
Vijay
