Internal Vref for ADC in LPC802

Hi,

I want to use ADC with 1V positive reference. My VCC is 3V3.

I can see VREFP input for external positive reference but is there any internal Vref like in ACOMP module ?

Thanks,

Asier.

Hello Asier,

Only the ACOMP module has an internal reference, so the ADC does require that you use the external reference.

My apologies for the inconvenience.
