1、I found that only P0[26] pin can be configured with DAC output.Is there only one DAC output pin on the chip?
2、The chip has a 10-bit digital analog converter,Is the maximum conversion value 1023?What happens if the conversion value is greater than 1023?
I'm looking forward to your reply!

It seems, this is the maximum you get in the LPC family. At least I did not find an LPC microcontroller with more than 1 DAC.
Dear 明杰 周, |
Thank you for your interest in NXP Semiconductor products and the opportunity to serve you. 1、I found that only P0[26] pin can be configured with DAC output. Is there only one DAC output pin on the chip? --- Yes, it's. 2、The chip has a 10-bit digital analog converter,Is the maximum conversion value 1023?What happens if the conversion value is greater than 1023? --- The maximum value is 1024 and the output voltage will be equal to the VREFP even loads a conversion value which is greater than 1024. Have a great day. ----------------------------------------------------------------------------------------------------------------------- Note: If this post answers your question, please click the Correct Answer button.
