Effects of a RESET
Connection Considerations
Transfer Function
A device reset forces all registers to their reset state. This forces the A/D module to be turned off,
and any conversion is aborted. The value that is in the ADRES register is not modified for a
Power-on Reset. The ADRES register will contain unknown data after a Power-on Reset.
If the input voltage exceeds the rail values (V
of the conversion is out of specification.
An external RC filter is sometimes added for anti-aliasing of the input signal. The R component
should be selected to ensure that the total source impedance is kept under the 10 k
mended specification. Any external components connected (via hi-impedance) to an analog
input pin (capacitor, zener diode, etc.) should have very little leakage current at the pin.
The ideal transfer function of the A/D converter is as follows: the first transition occurs when the
analog input voltage (V

Care must be taken when using the RA0 pin in A/D conversions due to its proximity
to the OSC1 pin.
