LPC1311/13/42/43

32-bit ARM Cortex-M3 microcontroller

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 Table 8:

• The ADC input trace must be short and as close as possible to the LPC1311/13/42/43

chip.

• The ADC input traces must be shielded from fast switching digital signals and noisy

power supply lines.

• Because the ADC and the digital core share the same power supply, the power supply

line must be adequately filtered.

• To improve the ADC performance in a very noisy environment, put the device in Sleep

mode during the ADC conversion.
