this result.
The ADC features a noise canceler that enables conversion during sleep mode to reduce
noise induced from the CPU core and other I/O peripherals. The noise canceler can be used
with ADC Noise Reduction and Idle mode. To make use of this feature, the following proce-
dure should be used:
Note that the ADC will not be automatically turned off when entering other sleep modes than
Idle mode and ADC Noise Reduction mode. The user is advised to write zero to ADEN before
entering such sleep modes to avoid excessive power consumption.
The analog input circuitry for single ended channels is illustrated in
source applied to ADCn is subjected to the pin capacitance and input leakage of that pin,
regardless of whether that channel is selected as input for the ADC. When the channel is
selected, the source must drive the S/H capacitor through the series resistance (combined
resistance in the input path).
The ADC is optimized for analog signals with an output impedance of approximately 10 k or
less. If such a source is used, the sampling time will be negligible. If a source with higher
impedance is used, the sampling time will depend on how long time the source needs to
charge the S/H capacitor, with can vary widely. The user is recommended to only use low
impedant sources with slowly varying signals, since this minimizes the required charge trans-
fer to the S/H capacitor.
