MP5748G using DAC in comparator

[karma_JC]

Hi:

Can we just use DAC in comparator to generate voltage on pin???

I'm using MPC5748G EVB, and configured CMP2 to generator a voltage on PB10.  The following is my code extraction for trying to generate the voltage on PB10:

CMP_DRV_GetDACConfig(INST_COMPARATOR2, &tDacConfig);

status = CMP_DRV_GetDACConfig(INST_COMPARATOR2, &tDacConfig);
if(status == STATUS_SUCCESS){
    	tDacConfig.voltage = 0x3F;
    	status = CMP_DRV_ConfigDAC(INST_COMPARATOR2, &tDacConfig);
    	data++;
}

Will this work????  Or, do you have example for this type of operation????

Thanks

James

Hi Petr:

If the is the case, is there any components in MPC5748G being able output "voltage" on a pin????

Thanks

Hi,

no, just digital signal, high and low level.

Hi,

as RM states... The DAC from a comparator is available as an on-chip internal signal only and is not available externally to a pin.
