LPC1315/16/17/45/46/47
32-bit ARM Cortex-M3 microcontroller
12.5 Reset pad configuration
12.6 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 17:
The ADC input trace must be short and as close as possible to the
LPC1315/16/17/45/46/47 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.
Remark: On the LQFP64 package, the analog power supply and the reference voltage
can be connected on separate pins for better noise immunity.
