11.5 Reset pad configuration
11.6 ADC usage notes
The following guidelines show how to increase the performance of the ADC in a noisy
environment beyond the ADC specifications listed in
Fig 31. Reset pad configuration

The ADC input trace must be short and as close as possible to the LPC11U2x chip.
Shield The ADC input traces from fast switching digital signals and noisy power
supply lines.
The ADC and the digital core share the same power supply. Therefore, filter the power
supply line adequately.
To improve the ADC performance in a noisy environment, put the device in Sleep
mode during the ADC conversion.
