I am interested in using the LPC1500 in a new design and need to know some ADC parameters not stated in the datasheet.
What is the acquision period of the SAR ADC in the LPC1500?
From that I can calculate analogue bandwidth and conversion period.

Hi,
The ADC controller uses the system clock as a bus clock. The system clock or the asynchronous ADC clock can be used to create the ADC clock which drives the successive approximation process:
A fully accurate conversion requires 25 ADC clocks.
I hope this helps,
Have a great day,
Soledad
