Sir,

I want to know whether we require multiplexing IC's like74LV573 or AS7S3266 for dedicated use of ADC and DAC in LPC2148. As we use these IC's for using ADC of AT89C5132. Or can we directly use the pins assigned to ADC and DAC? I want to use internal ADC & DAC of LPC2148, so is it needed to interface multiplexing IC's to it?

Thanks in advance. Your interest means a lot to me.
