Hello everybody,
I need some help about the LPC2368: I am using the internal DAC to control a dimm stage of several LEDs. I have tested several boards and I have recognized that there are extrem tolerances of the DAC output voltage. (I have programmed a digital start value in the µC's DAC register, it is the same in the different boards, also the external reference voltage of the DAC is OK. There are no real tolerances of the reference of the several boards). The DAC output voltage tolerances are bigger than described in the LPC2368's datasheet. (Unfortunately the datasheet gives actually not much information about the DAC) Does anyone of you have the same experience as I have?
Best regards Andreas
